Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat’s flow-shaping contour, enables recirculation patterns that extend into the furnace.get price
Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust willget price
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 furnacefor the combustion of solid fuels. Coal is ground to the size of a fine grain into the boiler, mixed witget price
