Efficient boiler plant operation requires a uniform mixture of coarse and fine coal across stoker hoppers to ensure even combustion. CONICAL® nonsegregating coal distributors will distribute the coal in a nonsegregating manner across the stoker hopper inlet, thus producing a uniform fuel bed, high average CO2, low combustibles in ash, higher boiler capacity, and lower maintenance.
Before - Photograph shows the fire on a chain grate stoker that is equipped with two flat chutes. Note the two fine coal zones with the attendant smoke and fuel going to the ash pit. Also note three coarse coal zones where the CO2 is low and where the uncovered stoker iron is exposed to high furnace temperatures.
After - Photograph shows the same stoker after it was equipped with two CONICAL® nonsegregating coal distributors. Note that the uniform coal feed produces a fire which is burning uniformly across the entire stoker, thus producing uniformly high CO2. Also note that the fuel is thoroughly burned out before the ashes are dumped into the ash pit.
