(HVAC) The duct work installed to bring fresh, outsiede air to the furnace and/or water heater. Normally 2 supplies of air are grought in. One high and one low.
Air used in the combustion process. Air contains oxygen which is required to combust fuel.
Air that provides the necessary oxygen for complete, clean combustion and maximum heating value.
Air that is supplied to combustion appliances to be used in the combustion of fuels and the process of venting combustion gases. Inadequate combustion air can lead to dangerous problems.
Air that chemically combines with a fuel during combustion to produce heat and flue gases, mainly carbon dioxide and water vapor.
An air supply brought into the furnace's combustion chamber - supplied from within the basement, or from outdoors. Combustion air is necessary to burn fuel.
The air supplied in an appliance specifically for the combustion of a fuel gas.
The duct work installed to bring fresh, outside air to the furnace and/or hot water heater. Normally 2 separate supplies of air are brought in: one high and one low.
The air fed to a fire to provide oxygen for combustion of fuel. It may be preheated before injection into a furnace.
Air that is used for the burning of a fuel.
Fresh outside air which is strictly used for combustion type appliances - furnace, water heater, etc.
Since a fire needs oxygen, this term refers to the air introduced into an appliance to aid the combustion of fuel.
Air necessary for complete combustion of a fuel, including theoretical air and excess air.
Amount of air necessary to burn available fuel.
