Abstract: The present invention relates to a process for reducing coal consumption in coal fired plant with fluidized-bed drying, namely a fluidized-bed drying system is provided between a coal powder bunker as well as a weighing belt and a coal grinding mill of the prior coal fired boiler generating set, and superheated steam which has done partial work is extracted from an steam turbine and used as a drying medium, moisture contained in the coal powder is evaporated with sensible heat and latent heat of the superheated steam, water resulted from the condensation of the superheated steam is fed into a deaerator of the steam turbine via a condensate pump for recirculation. The present invention has advantages of reducing coal consumption and saving coal, recovering residual heat, reducing emission of carbon dioxide and adopting to the national industrial policy on energy saving and emission reduction.

Abstract: The present invention relates to A drying process for drying lignite by swashing dust collection and washing, comprising steps of: conveying wet powdered coal into a dryer by a feed belt so as to be dried; introducing hot steam for drying via a rotary joint at an outlet end of the dryer and into a heat exchange tube via a steam chamber; having the wet powdered coal contact and heat exchange with a steam pipe and dried; discharging the dried coal from an discharge port and conveying the dried coal to a subsequent station by a discharging belt; introducing condensed water resulted from steam heat exchange into a condensate pot via a rotating joint and then conveying the condensed water to a next station via a condensate pump; performing a primary dust collecting in a bin at a tail end of the dryer on waste gas produced during the drying process, discharging the waste gas from a top end of the bin and the introducing the waste gas into a swashing dust collector; discharging waste liquid resulted from washing the
