The Importance of Operating with Proper Furnace Draft

Aug 26, 2020 · Most power plant boilers have balanced draft furnaces. This means there is a fan (or fans) that supplies combustion air to the boiler furnace, known as a forced draft fan, and another fan that pulls the exhaust gases (flue gas) from the boiler furnace 1, known as an induced draft Fan. These fans work together to maintain pressure (or draft) in the furnace slightly less than atmospheric

Control Of Criteria and Non-criteria Pollutants From Coal

Most of the trace elements emitted with the flue gas are associated with the fly ash, though some may remain in the vapor phase. The amount of trace elements emitted from a particular boiler depends on: combustion temperature, fuel feed mechanism, characteristics of the flue gas, and CWM properties (trace element concentration).

The boiler was driven by flue gas exiting from a gas turbine. Because the temperature field (see the measurement array shown in Figure 9) was almost uniform, the corresponding boundary condition was specified in both the models discussed further as a constant. The outlet temperature of flue gas was estimated by the operator because the

Flue gas - Wikipedia

Flue gas is the gas exiting 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, the flue gas 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
