Coal Fired Boilers | Kempton Steam Museum

These boilers were fired mechanically using a rolling chain grate driven by either electricity or steam. Coal from hoppers in the roof fell down chutes via gravity onto the slow moving chain. The chain then carried the coal under the water tubes where it heated the water. As the chain carried the coal it would burn and eventually turn to ash.

1.1 Bituminous And Subbituminous Coal Combustion

coal requiring 20% more pounds of coal could easily exceed the burning capacity of the stoker such that output of the steam generator may be reduced. In short, lower Btu coal will increase the pounds of coal to be handled and when the variations are large enough we can expect a reduction in boiler capacity. Higher Btu coal seldom gives any pro-
