[email protected]The pulverized coal is concentrated and uniformly supplied by the milling factory, with stable coal quality.Pulverized coal combustion is sufficient, boiler heat transfer effect is good, air excess coefficient is small, and system thermal efficiency is high power consumption equipment with large power is equipped with frequency converter, and the power saving effect is obvious.
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.
