Importance of Keeping Heat Exchanger Clean

The heat exchanger air-water purification is an absolute necessity so that the system of production runs. If your heat exchanger will not be as clean as it should be, he is unable to properly operate and exchange of heat, could not take place. This leads to significant problems in the line if it is not treated within a short time. However, with the cleaning alone is not sufficient to keep everything in perfect condition.

An air-water heat exchanger is very specialized devices intended for use when the air or in the air, the temperatures are higher than 130 degrees Fahrenheit. Air conditioning industry is not the machine to cool when the ambient temperature is at this level, since the refrigerant compressor of its production to about 150 degrees Fahrenheit, and there is too little difference between the two temperatures for the coolant to his job. In such cases, the air-water heat exchanger in question. They bring in the chamber in the courtyard below the temperature of the air, so that the device is not working correctly.

Basically, a heat exchanger air water cleaning is simply to ensure that both air and water to a portion of the thermal processes of your system are clean. For example, if the mechanism of the system brings the air is a cooling tower, you must bear in mind when he brings the air in the system, the debris, which is not in the air in the system with him. These deposits may be in the system, the establishment in her, and limited the operation - and possibly causing a malfunction, and even heavier. So, quite simply your own system seems to heat the solution to this problem.

However, the ratings are compared, what the adoption of a cold tablet, if you have a cold, and rightly so. Even if the cleaning of the heat exchanger of the system ensures that they are free of everything, leading to problems, whether it is doing nothing to prevent the problem does not occur, particularly in areas where there is a lot of scrap , potentially leading to a kind of jam. In this sense, the cleaning is not enough.

The ultimate solution would be an excellent technology Filtersystem keep residue in the system, primarily, and cleaned with care.

So, make the installation of filters and the technology of filtration and devout your water air heat exchanger for cleaning your entire system to function optimally.

Plate Heat Exchangers - Design, Advantages and Disadvantages

Plate heat exchangers are obviously types of heat exchangers. It functions by transferring the heat from one fluid to another through the use of metal plates. Comparing it with conventional heat exchangers, these ones are favored specifically because the fluids work on larger surface areas and are capable of dispersing to the metal plates. Simply put, the procedure enables proper facilitation of heat transfer as it speeds up the changes in temperature occurring during the process.

Knowing more about the concept of plate heat exchangers involves looking at the design of the tool as well as setting apart the advantages from its disadvantages. Basically, a heat exchanger uses pipes in order to cool or heat a fluid through the process of transferring it to another fluid. The pipes' walls are often made either out of metal or other substances known to be of high thermal conduction capabilities. This is to ensure that the transfer of heat from one fluid to another will be properly facilitated. Another coating is found outside the pipe walls, now made of plastic with thermal insulation to suppress the heat from coming out of the exchanger.

Design of plate heat exchangers

From the conventional design of heat exchangers, a plate heat exchanger is said to be more of a specialized one. The design was made to construe with its purposes of heat transfer for two types of fluids. For the heat exchanging process, semi-welded, brazed or welded exchangers are used. Instead of making use of a regular pipe, two chambers are used and are separated by the so-called corrugated metal plate.

The plate is designed out of stainless steel. This material has the ability to withstand corrosion and high temperature while it is also noted for its durability and strength. In between the plates, rubber sealing gaskets are placed.

A look at its advantages and disadvantages

The advantages of this type of heat exchangers are seen through its compactness, flexibility and ease of cleaning. Its compactness can be attributed to the fact that the entire output does not require a large floor space. Its flexibility is seen with its ability to cope with requirements of different types of fluids. The plates are removable thus making it easy to clean. If replacement is needed, the plates may be removed conveniently as well.

The main disadvantages of plate heat exchangers are classified into three. First, long gaskets are needed. Second, leakage is probable. And lastly, operation costs as well as investment should also form part of the consideration.

Marine Diesel Engine Maintenance - Engine Cooling

Understanding the marine diesel engine cooling system is a necessary part of marine diesel engine maintenance.

Raw Water Cooling

Flexible impeller pumps provide an efficient solution to most raw water pumping needs. The primary advantage of a flexible impeller pump is that it is self-priming, which means that when the vanes of the impeller are depressed and rebound, they create their own vacuum, drawing fluid into the pump. A dry pump can lift water up to as much as three meters. Thus a flexible impeller pump being used for engine cooling does not need to be manually primed or located below the water line. An added feature of a flexible impeller pump is that it can pass fairly large solids without clogging or damaging the pump. This reduces the need for filtration of incoming fluids.

For general or fresh water applications, a standard long lasting neoprene rubber impeller is used.

A general feature of all flexible impeller pumps is that they cannot be permitted to run dry for more than 30 seconds. Both the impeller and the seals require water for lubrication and will soon burn out if run dry. Parts that start to show wear are easily replaceable and service kits are readily available for most models.

Fresh Water Cooling

For circulation of the internal, closed, fresh water circuit of the cooling system it is common to use a flexible rubber pump if it is located on the cold side of the system (max. 55°C). Other types of belt-driven centrifugal pumps are also used. The closed circuit normally transfers heat from the engine to the heat exchanger. The liquid used is water and anti-freeze.

Cooling Capacity

The required output of the cooling pump is related to engine type and size, not to the size of the heat exchanger and exhaust system. This is true for both raw water as well as fresh water handling systems.

Temperature Regulators (Thermostats)

Thermostats are usually placed in the outlet at the top of the cylinder head to prevent the coolant from moving to the header tank until the marine engine has nearly reached operating temperature.

There are different types of thermostats, the most common being the wax pellet type. The capsule on the lower part of the thermostat has a mixture of wax and copper (to increase the thermal conductivity) sealed in it. As the coolant temperature increases, the wax expands and forces a rod to open the poppet valve at the top of the thermostat, which allows the coolant to circulate.

Cooling system checks

• To test your thermostat, boil a pot of water and drop in the thermostat. (The water must be 100°C--the thermostat usually opens at 85°C.) If the thermostat opens it is okay. If it doesn't open, replace or clean carefully as they can become sticky with deposits. Yanmar thermostats can and should be regularly serviced. Some thermostats cannot be serviced.
• If the thermostat doesn't work, do not remove it and run the engine without it, as the engine will run cold and tight. You can drill a series of 1/4˝ holes to give equivalent flow to an open thermostat. This will get you home, but you must then replace it. Be careful not to fit thermostat upside down.
• Thermostat housings often corrode and need to be replaced. Some can be fabricated.
• The cooling system should be checked after 100 hours running, or at least once each season, for leakage, deposits, etc.
• The thermostat can be taken out of the housing on the front of the engine.
• The heat exchanger core should be removed bi-annually for cleaning and inspection.
• Many heat exchangers are fitted with anodes to protect the expensive core. Check regularly.
• Check all hoses and clamps regularly.

Replacing the sea-water pump impeller

The pump impeller is made of neoprene rubber and this can be damaged in the case of water deficiency if, for example, the sea-water intake should be blocked. The pump impeller is changed as follows:

1. Remove the cover from the sea-water pump. Note that there is the risk of water getting into the boat. With the help of two screwdrivers pull the shaft with the pump impeller out of the housing as far as necessary to reach the bolt retaining the impeller. Place some kind of protection under the screwdrivers in order not to damage the impeller housing. Alternatively, using channel-lock pliers, slide jaws between blades of impeller, rotate and withdraw.
2. Pull the impeller off the shaft. Clean the inside of the pump housing and fit the new impeller. Always have a spare impeller on board.
3. Check that the pump coupling is not damaged, by trying to turn the pump impeller. Fit the cover with the original gasket, which has the right thickness.

Check out the impeller trouble shooting guide to discover how to repair and replace a sea water pump impeller. Did you know that if you understand the basics of marine diesel engine maintenance you can service your own marine engine and save on maintenance costs? Every boat owner should have at least a minimum understanding of their marine engine. Keep your family safe on the water, find out how to service your marine diesel engine yourself and know that it is properly maintained.

Does a Dirty Furnace Filter Impact Equipment Performance?

Unfortunately one of the most often neglected maintenance tasks for residential heating and air conditioning systems is changing the furnace filter. A furnace filter is an extremely important component of any air conditioner or furnace.

Many people use the cheap disposable fibreglass furnace filters thinking they are getting good value for their money. The reality is that these filters are next to useless because they don't remove enough dust from the air to make much of a difference.

There is greater value in using one of the more efficient varieties of furnace filter available and there are many to choose from, beginning with the most commonly used pleated furnace filter to some of the lesser known specialty filters commonly used in many homes.

Why is the furnace filter so important?
There are several very important things that happen when people don't change their furnace filter or air conditioner filter. You often hear that not changing your air conditioner filter or furnace filter will cause problems.

What really happens?

Air Conditioner Filter

• Reduced refrigerant operating pressures within the air conditioner which can cause the evaporator coil to ice up.
• Reduced cooling capacity which results in longer run times and higher energy costs.
• Poor air circulation throughout your home resulting in some spaces not being cooled properly

Furnace Filter

• Reduced air flow across the heat exchanger resulting in higher heat exchanger operating temperatures. This can result in cracked heat exchangers causing Co to leak into the space being heated.
• Increased run times due to lower air flow. This results in higher fuel costs because it takes longer to heat the space. In electric forced air furnaces the result is the same except your power bill will be higher.

A common belief is that the blower fan also has to work harder when the furnace filter is dirty but this claim is only made by people who don't really understand the operating characteristics of a centrifugal fan.

How often should you change your furnace filter?
To ensure that your furnace or air conditioner continues to operate at maximum efficiency it is very important to replace or clean your air filter at least every three months for one and two inch filters. Four inch filters can often be left in the system longer depending on the filter efficiency and several other factors.

Which replacement furnace filter is the best?
Selecting the best furnace filter is not an easy thing to do because there are so many variables to consider. There are filters to meet virtually every need. Allergy sufferers may require a very efficient filter, while a person who has no allergies only requires a moderately efficient filter. Maybe you don't have allergies but you hate dusting and that is what guides you in making your decision.

To make things even more complicated, there are even duct mounted air purifiers that you can use in conjunction with a your furnace filter. These help to purify the air even further.

These are questions which should be asked when thinking about purchasing a new electric heat pump for your swimming pool or spa.

- How many BTUs will you need?

- Do you have the electric service required for a heat pump?

- Is there sufficient space available to install a heat pump?

- What type of features do I need?

- Plastic or metal cabinet?

- Titanium heat exchanger?

- Digital controls or analog?

Let's try to answer the questions above thus allowing for an educated purchase of your new pool heater.

- How many BTUs will you need? - The size of your pool (amount of gallons and surface area square footage will dictate the BTUs required to heat the pool or spa in the most efficient manner. Also take into consideration the amount of strong wind which will effect your pool and whether or not you will be using a pool blanket to help hold the heat into the pool. Check the manufactures recommended sizing chart to help determine the correct size and model for your application.

- Do you have the electric service required for a heat pump? - Most heat pumps required 220Volts of electric and many require separate 50 to 60 amp breakers. Check with your electrician to make sure you have sufficient electrical power to operate your new heat pump.

- Is there sufficient space available to install a heat pump? - Most heat pumps will require a "footprint" area of about 40" x 40" and about 40" in height. Heat pumps need good air circulating space area around the units to allow for peak operation.

- What type of features do I need? Today's heat pumps are manufactured with many different features, some are, Dual thermostats (great for a pool and spa combination), Scroll compressors, Extra quiet fan motors, Extended warranties, Built in water bypass valves, Ability to operate motorized valve actuators, Easy to see readouts with diagnostic trouble shooting messages, and many more. Check the manufactures literature to make sure you are choosing the heat pump with the features best suited for your application.

- Plastic or metal cabinet? Is you pool located in a location which would be better suited for a plastic cabinet?

- Titanium heat exchanger? The heat exchanger is the piece of equipment located inside the heater which the pool water flows through. Titanium is a forgiving material in that it allows for a greater tolerance of water chemistry problems. Other types of heat exchanger material is much more susceptible to problems with poor water chemistry. Please note: Proper water chemistry is a must when using any type of pool heater.

- Digital controls or analog? The controls on the heater can be digital electronic or analog. Once again it is best to consult the manufactures literature to gather which would be best for your application.

A swimming pool or spa heat pump is a large investment and should be researched carefully. Purchase the correct unit and you can expect many years of warm enjoyable water to swim and relax in.

Why You Need a Fireplace Heat Exchanger

A fireplace is an enjoyable way to heat your home, but it's also not a very effective one if you are not using a fireplace heat exchanger. Most people that use a fireplace to heat their homes don't even realize that it is not heating their home efficiently. Of course, by improving the performance of your fireplace, you will also be saving on the cost of heating your home.

When you use a fireplace to heat your home, the fire must conduct air in order to keep burning. The air being drawn into the fire is the warm air from your home, and that air is being replaced by cold air from outside your home. In essence, your are creating a air current cycle that brings cold air into your home and pushing fire heated air out through your chimney.

Of course, there are dangers involved in building a fire inside your home, so you will want to follow all necessary safety precautions when using your fireplace. However, if you really want to keep your home warm in winter, watching your heat go out the chimney and get replaced by cold, outside air is not the best way to do it. In fact, very many people even wonder how it is that others are able to keep their homes nice and warm with their fireplace.

The answer is to use a fireplace heat exchanger. By using a fireplace heat exchanger, you will be able to stop using the warm air in your home to fuel the fire and start having the fire warm the air in your home. These devices force air, heated by your fireplace, directly back in the the room that the fireplace is in. Instead of all that hot air escaping, it is pushed right back into your home, where you really want it.

In most cases, you will need to spend about 500 dollars to get a fireplace heat exchanger.While that is a big expense, so is the firewood you are burning to heat the sky above your chimney. By making your fireplace able to heat your home more efficiently, you are saving a bundle of money in the long run.

You can learn more about fireplace heat exchangers, as well as the importance of furnace heat exchangers cleaning on my heat exchanger cleaning equipment site.

Interesting Facts About Wood Furnaces

Wood furnaces are direct fire heaters. It is a convenient and economical way of heating homes. Many Americans, Europeans, Canadians and people from other countries who experience very cold weather or climate use this kind of unit.

Many users nowadays prefer using wood furnaces to save the Earth from greenhouse effect. Burning bio-mass fuels does not increase the risk of carbon dioxide in the atmosphere. Since wood is a renewable resource safe for the environment, it can also conserve energy.

There are three main types of wood furnaces. First is the Central Wood Furnaces. It can be installed inside the house, garage, mechanical room or at the basement. It uses either a type of forced-air or hot-water system to distribute heat throughout the house.

The second type is the Multi-Fuel Furnaces. This unit can be placed inside or outside the house. It enables the burning of different kinds of fuel like coal, oil, gas and wood. These types are flexible that can work as a back-up option, especially when using other kinds of fuel. It is appropriate in cases where there is only one chimney outlet available. The machine allows venting of the wood as well as the fossil fuel so as to exhaust-up the same pipe.

The third type is the Outdoor Furnace or Boilers. This unit utilizes firewood, particularly when there is a huge supply. It keeps the smoke, mess and bugs outside. The furnace is similar to a small utility building. It is a wood burning furnace placed outdoors. It can be found along the yard, between 50 and 150 feet away from the house.

The furnace firebox is surrounded by a water jacket. As heat is released, it is transferred from the fire onto the water. It is then pumped through insulated pipes and placed underground, then into your house. Finally, heat radiates to warm up the entire house.

On the downside, this unit needs some boots, gloves and a cap to slog out onto the blowing snow to keep it going. Many outdoor boilers are hard to control for a clean burn due to their oversized firebox. Aside from this, it tends to smoke a lot during automatic restart after a long off cycle.

All these wood furnaces are controlled by a thermostat similar to other heating systems. Different heating systems are used on working on these types.

The forced hot-air systems use heat exchangers. The warm air spreads out with ductwork. Burning fuel causes the heat exchanger to heat-up. However, there is no heat storage capacity in this system. The unit needs to be re-fueled everyday to maintain its temperature during the cold months. It is also easy to add filtration, air-conditioning and humidification because the air in this system is being re-circulated. Hydro-air units use ductworks to help distribute air similar to forced hot-air systems. The heat exchanger is replaced by a hot water coil being heated by a hot water loop from its boiler. There are multiple hydro-air units that can be fed by a single boiler throughout the sections of the house for different cool zones. This kind of system is always combined with air-conditioning.

A combination central-heating unit system is designed to burn wood, oil or gas. It relies on the back-up fuel when the wood is not convenient for usage. Both combustion chambers can be maximized with this design. The two fuels are not usually used simultaneously. It can either be hot-air or hot-water furnaces. The disadvantage of this unit is that it tends to be twice as expensive as a single-fuel heater. This dual system offer maximum fueling flexibility.

Wood furnaces have disadvantages also. Some needs to be refueled several times and are a bit dirty to operate. It is also not always convenient to gather fire woods. And to produce good heat, you must know how to stack these pieces of wood properly. Lastly, all these units require electricity due to its thermostat.
