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.
Now that we’ve discussed what a boiler is, you may be wondering why one is needed and what the plants actually do with the steam that is produced by boilers. It will vary somewhat depending on the plant, but for the most part the steam produced by the boilers will serve one of the following functions:
Town gas is a flammable gaseous fuel made by the destructive distillation of coal.It contains a variety of calorific gases including hydrogen, carbon monoxide, methane, and other volatile hydrocarbons, together with small quantities of non-calorific gases such as carbon dioxide and nitrogen, and is used in a similar way to natural gas.This is a ...
The steam can come from a variety of sources, like a natural gas or solid fuel fired boiler in the plant, excess steam from a power plant, or steam coming off an electricity-generating turbine. In its young existence as Davenport Dryer, the company has built and shipped 16 dryers in the past two years.

draft loss and pressure drops in the gas and air circuits are kept at low values to reduce fan power requlrements. Because of the high cost of fuel, very few, if any, medium and large size boilers are sold today without heat recovery equipment. Heat recovery for a stoker fired boiler consists of either an economxzer or an airheater, or both.
Producer gas is the mixture of gases produced by the gasification of organic material such as biomass at relatively low temperatures (1292º to 1832º F). hydrogen (H. 2), carbon dioxide (CO 2) and typically a range of hydrocarbons such as methane (CH 4) with nitrogen from the air. Producer gas can be burned as a fuel gas such as in a boiler ...
