For thermal power enterprises having cirulating fluidized bed (CFB) boilers

additional dry distillation system can supply medium calorific value coal gas for civilian use; for a local thermal power plant having insufficient heat load and situating at a twon area

watergas generating furnace can be allocated to supply coal gas for the city and twon. The said two schemes can all implementing heat

electricity

and coal gas triple cosupply

having two benefits of energysaving and environment protecting functions

enhancing the utilization coeficient of thermal power units.
