Pulverized coal (pulverized fuel-pf) has been fired in rotary cement kilns (see Kilns) and boiler furnaces (see Boilers).The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture. The coal is pulverized to a fine powder, usually so that 70% is less than about 75 μm in size, before being carried by part of the combustion air stream to the ...
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.
coal pulveriser for reheating furnace. A pulverized coal–fueled boiler is designed with a large furnace cavity that to 1,100F superheated steam and reheated steam outlets, the furnace exit gas . fuel imbalances at the furnace exit is coal pulverizer performance.
The reheating furnace consists of a heating furnace body, a cooling system, a combustion system, an inlet and outlet, a smoke exhaust system, a preheating recovery system, and an automatic control system. Usually, the fuel of the furnace is gaseous fuel, natural gas, heavy oil or pulverized coal, some burning lump coal, etc.
