Abstract

The invention relates to a lignite fired steam power plant comprising a water/steam power cycle, a dryer system for drying lignite coal and a heat recovery system for recovering thermal energy from the dryer system. The heat recovery system vaporises condensate against a vapour line of the dryer steam and then compresses the vaporised condensate for use to preheat either or both combustion air or condensate of the water/steam power cycle.
