ing). Pulverizer blueprinting is a prerequisite for balanced fuel flow through the burner lines. Keep in mind that coal is about a thousand times denser than air and is a solid. The smaller the particles, the more the solid fuel par-Measuring Coal Pipe Flow Coal pipe flows can only be balanced and optimized when they are measured.
A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
In this system, each burner or a group of burners and pulverizer constitute a unit. Crushed coal is fed to the pulverizer through feeder at a variable rate governed by the pulverizer through feeder at a variable rate governed by the combustion requirements of
