The gas vented from a boiler by the stack. Flue gas contains the waste gases from the combustion of a boiler's fuel.
The exhaust gases from a combustion facility in the stack that discharges them to the atmosphere. These gases often contain sulfur, which can be removed by a desulfurization scrubber, and particulates, which can be removed using specialized collectors like electrostatic precipitators, mechanical collectors (cyclones), fabric filters (baghouses), and wet scrubbers.
See GAS, FLUE.
Gas that is left over after fuel is burned and which is disposed of through a pipe or stack to the outer air.
The mixture of gases and fly ash leaving the furnace in a coal-based boiler.
The gases emitted to atmosphere from a production or combustion process through the flue or "smoke stack"
All gases and products of cornbustion exhausted through the flue or chimney.
A mixture of gaseous products resulting from combustion of the fuel. Forced Draft Use of a fan to supply combustion air to the burners of a heater and to overcome the pressure drop of the burners and any air preheat equipment.
Products of combustion plus excess air plus dilution air (on natural-draft appliances) that pass through the vent.
The air coming out of a chimney after combustion in the burner it is venting. It can include nitrogen oxides, carbon oxides, water vapor, sulfur oxides, particles and many chemical pollutants.
The gaseous products of combustion in the flue to the stack.
The gas resulting from the combustion of a fuel that is emitted to the flue.
Flue gas is gas that exits to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, it refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived from the combustion air, carbon dioxide (CO2) and water vapor as well as excess oxygen (also derived from the combustion air).
