RCTFlueGasTreatment | CleanBoiler.org

NOx control with flue gas treatment involves the reduction of NOx in the flue gas by injecting a chemical reducing agent into the post-combustion region of a combustion unit. The reducing agents, primarily ammonia and urea, convert the NO in the flue gas to molecular nitrogen at high temperatures, between 1,600 and 2,000°F, without a catalyst.

Protecting Boilers Against Flue Gas Condensation | 2017-08

Power-station boilers produce most quantities of flue gas and a great deal of thought has been given to burner design to keep down flue temperatures. Various arrangements are being used in power-station boilers to reduce NO x formation and emission. 1. Use of low nitrogen content fuels.

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

Adapting Boilers to Utilize Landfill Gas: An

Flue Gas Recirculation and Excess Air. Present-day packaged steam generators operate at high excess air (15-20%) with flue gas recirculation (FGR) rates ranging from 0% to 30% to limit CO and NOx. Flue gas recirculation refers to the admission of flue gases from the boiler exit back into the burner region in order to lower the combustion temperature, as shown in Fig. 4.6, which in turn lowers NOx.

Jan 09, 2013 · FGR is the process by which exhaust gas is introduced into the combustion-air stream prior to a burner. Flue gas also is relatively cool (300°F to 550°F, depending on the design of the boiler and whether there is a feedwater economizer) with respect to flame temperature, and flue gas has little oxygen from the combustion process.
