CHP is used in every state and in the District of Columbia at over 4,100 facilities includingcoal 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-In parallel co-burning, coal and biomass are combusted using separate boilers. Another option for reducing the amount of harmful emissions is the use of coal-water slurries coal-water fuels. They are characterized by low combustion temperature, thereby reducing the nitrogen oxide emissions by as much as 70. Existing Methods of Coal Grinding
