firing scheme. Raw coal from the existing bunker is fed to a pulverizer by a metering feeder and milled and dried with a quantity of hot sweep gas extracted from the boiler exhaust. The sweep gas and powdered coal are then separated in a bag house. The dry powdered coal is collected in the bag house hopper. The spent sweep gas containing the

Burners and overfire air (OFA) - Babcock & Wilcox

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 staging
