Furnaces and Boilers | Department of Ener

Most U.S. homes are heated with either furnaces or boilers. Furnaces heat air and distribute the heated air through the house using ducts. Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil.

Burn Wise | US E

Burn Wise is a partnership program of the U.S. Environmental Protection Agency that emphasizes the importance of burning the right wood, the right way, in the right appliance to protect your home, health, and the air we breathe.

Using Your Wood Stove Efficiently and Effective

Fortunately, it is not too tough to operate wood-fired heating equipment well. If you take a little time to follow the four simple tips outlined above, you will find that not only is your stove running at a higher efficiency, but the air in and around your house will be cleaner …

Three Ways to Optimize Solid Fuel Combustion - Hurst Boil

If there is a lack of over-fire air, large quantities of carbon monoxide and other combustibles will travel through the system and out of the stack. This waste of fuel results in heat loss and decreases efficiency. An over-abundance of combustion air results in heat loss …

WOOD GASIFICATION - WRBoile

Combustion Efficiency and Thermal Efficiency The overall efficiency of a wood fired boiler is the result of the combustion efficiency and of the ability to transfer the resulting heat to the boiler water. With wood gasification, combustion efficiencies of 90% can be realized. This results in a tremendous amount of heat.

Energy Efficiency and Your Wood-Burning Appliance | Bu

Wood heaters manufactured before 1990 burn wood less efficiently, which wastes fuel, pollutes outdoor air and creates dust in your home. Replacing an old wood heater or fireplace with a more energy efficient EPA-certified appliance can save fuel, money, and protect you and your family's health.

Boiler Combustion | CleanBoiler.o

As a safety factor to assure complete combustion, boilers are fired with excess air. One of the factors influencing NOx formation in a boiler is the excess air levels. High excess air levels (>45%) may result in increased NOx formation because the excess nitrogen and oxygen in the combustion air entering the flame will combine to form thermal NOx.

The Outdoor Air Myth Exposed - Wood He

Since the air consumption of a wood stove is so low, the risk of reversal of a ducted combustion air supply outweighs any advantage gained by bringing air from outdoors. An open fireplace, in contrast, can exhaust such a large volume of air that it could affect the operation of, for example, a conventional gas-fired furnace or water heater.

Combustion Efficiency and Excess Air - Engineering ToolB

Excess air increase the amount of oxygen to the combustion and the combustion of fuel. when fuel and oxygen from the air are in perfect balance - the combustion is said to be stoichiometric The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion.

Improving Boiler Efficiency - Energy Dep

Properly operated boilers require a certain amount (10% to 20%) of excess air to ensure complete combustion. However, operating with too much excess air reduces boiler efficiency by heating up and throwing away this "cushion" of excess air.
