Title:
ENERGY RECOVERY DEVICE AND COAL GASIFICATION POWER GENERATION PLANT
Document Type and Number:
WIPO Patent Application WO/2012/074061
Kind Code:
A1
Abstract:
An energy recovery device (10) comprises a heat exchanger (14) which carries out the heat exchange between low-pressure condensed water (12) supplied from a regenerative superheater (11) and supply water (13) and a compressor (17) which compresses and superheats low-pressure steam (15) that has been heat-exchanged by the heat exchanger (14) to generate medium-pressure steam (16), wherein, when the low-pressure condensed water (12) has a pressure of 0.3 MPag and a temperature of 140-150°C, the low-pressure condensed water (12) is heat-exchanged with the supply water (ambient pressure, 30°C) (13) to generate the low-pressure steam (15) having a pressure of 0.2 MPag and a temperature of 120˚C and the pressure and temperature of the low-pressure steam (15) are increased by the compressor (17) to generate the medium-pressure steam (16) having a pressure of 4.0 MPag and a temperature of 300°C.
