Abstract: The invention relates to a dryer system for drying lignite coal used in a power plant. The system comprises a dryer and a closed loop heat pump circuit that is configured and arranged to provide heat energy to the dryer. The closed loop heat pump circuit includes a working fluid, a dryer heat exchanger, an expansion device fluidly connected and downstream of the dryer heat exchanger, arranged to enable heat energy transfer from the vapor of the second outlet line to the first working fluid and a compressor for compressing the working fluid.

Abstract: An Air Separation Unit is disclosed which is thermally integrated into a coal fired oxy boiler power plant. The Air Separation Unit has a Dryer with a dryer heater, wherein an extraction line connects the steam extraction port to the dryer heater. A drain line of the dryer heater then fluidly connects the regeneration heater to a point of a Rankine steam cycle fluidly within the condensate system.

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.

Abstract: The invention relates to a lignite fired steam power plant comprising a water/steam power cycle and a lignite dryer system having a heat pump circuit configured and arranged to provide heat energy to a lignite dryer of the dryer system. The heat pump includes a dryer heat exchanger, an expansion device and an evaporator heat exchanger connected to the first outlet line so as to enable heat energy transfer from the vapour of the first outlet line to the first working fluid. A compressor is also included in the heat pump circuit. In addition the heat pump circuit is connected to the water/steam power cycle by a steam makeup line from the pressure series of steam turbines and a condensate return line.
