摘要： 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 (10). The closed loop heat pump circuit includes a working fluid, a dryer heat exchanger (13), an expansion device (17) fluidly connected and downstream of the dryer heat exchanger (13), arranged to enable heat energy transfer from the vapour of the second outlet line (16) to the first working fluid and a compressor (21) for compressing the working fluid.

摘要： The invention relates to power plant with a steam water power cycle and a lignite dryer that uses steam from the steam water power cycle. The connection of the lignite dryer to the steam water power cycle includes a first extraction line (104) and a second extraction line (101). The first extraction line (104) originates from a point between a high pressure turbine (32) and an intermediate pressure steam turbine (34) and includes an ejector (106), while the a second extraction line (101) originates from a point an intermediate pressure steam turbine (34) and a low pressure steam turbine (35). The configuration and location of the ejector (106) and the connection of the second extraction line (101) to the ejector (106) enables a lower pressure steam in the second extraction line (101) to be fed into the heater (13) together with a higher pressure steam of the first extraction line (104).

摘要： 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 (10) of the dryer system. The heat pump includes a dryer heat exchanger (13), an expansion device (17) and an evaporator heat exchanger (19) connected to the first outlet line (16) so as to enable heat energy transfer from the vapour of the first outlet line (16) to the first working fluid. A compressor (21) 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 (27) from the pressure series of steam turbines and a condensate return line (29).
