Conversion of Coal

Coal to natural gas conversion projects are subject to a number of environmental regulations and permitting requirements The primary regulation that can dictate the air pollution control technologies required for the new natural gas-fired boiler is the New Source Review (NSR) Prevention of Significant Deterioration (PSD) permitting requirements...

Biomass Cofiring in Coal

Cofiring biomass and coal is a time-tested fuel-switching strategy that is particularly well suited to a stoker boiler, the type most often found at coal-fired federal facili-ti However, cofiring has been successfully demonstrated and practiced in all types of coal boilers, including pulverized-coal boilers, cyclones, stokers, and fluidized ....

Burners and overfire air (OFA)

Since 1971, B&W has sold low NO x combustion systems for more than 120,000 MW of generating capacity in both new and retrofit boiler applications Our low NO x burner technology has been successfully applied to a broad range of B&W and non-B&W units with varying fuel characteristics and boiler arrangements We also pioneered the development and application of NO x ports and air ,...

New Technology of the Ammonia Co

And it succeeded to reduce the NO concentration to be in the same degree with the conventional boiler Since the coal fired boiler originally has the countermeasure to deal with the tiny amount of the ammonia contained in the coal, the concept of such low NO technology can be easily diverted into the ammonia co-firing...
