Boiler Efficiency and Combustion | Spirax Sarco

Pressure from legislation regarding pollution, and from boiler users regarding economy, plus the power of the microchip have considerably advanced the design of both boiler combustion chambers and burners. Modern boilers with the latest burners may have: Re-circulated flue gases to ensure optimum combustion, with minimum excess air.

Boiler Combustion | CleanBoiler.org

In industrial boilers, NOx is primarily formed in two ways; thermal NOx and fuel NOx: Thermal NOx is formed when nitrogen and oxygen in the combustion air combine with one another at the high temperatures in a flame. Thermal NOx makes up the majority of NOx formed during the combustion of gases and light oils.

and steam energy. Industrial boilers use a range of fuels depending on boiler size and design characteristics and on the availability/proximity of fuel. In many cases the fuel is a by-product or waste product from other processes. The volume and nature of emissions from combustion in boilers differ depending on fuel composition,

David A. Tillman, in Coal-Fired Electricity and Emissions Control, 2018. 2.1.3 Control of NO x. Fluidized bed boilers of all types are, by virtue of their combustion temperatures, low NO x generators. Operating the reactors at temperatures ≤1700°F virtually eliminates formation of any thermal NO x.All NO x is generated from the conversion of fuel nitrogen.
