Boiler Cycling Considerations - Babcock & Wilcox
Acceptable air-fuel mixing is achieved at reduced boiler loads by operating with fewer burners in service and by operating those burners at higher firing rates. Burner mixing can be induced by using the primary air/pulverized coal stream, by using the secondary air, or by a combination of the two.
