Optimising fuel flow in pulverised coal-fired boilers

Poor pulverised fuel (PF) distribution to the burners in a coal-fired boiler reduces combustion efficiency, increases wear of equipment and emissions, and so is bad for the economics of a plant.

Low Volatile Coal - an overview | ScienceDirect Topics

Vertical down-shot firing is used where volatile matter of coal is low, usually 18% or below. Low volatile coal takes longer to complete combustion and does not require high turbulence as in horizontal firing. The coal and primary air is fed vertically downward from the burners near one side of the furnace roof.
