圧縮空気貯蔵発電装置及び方法
Document Type and Number:
Japanese Patent JP6817908
Kind Code:
B2
Abstract:
To make power generation possible with a high performance and quickly even when restarting utilization after long term stopping.SOLUTION: A compressed air storage power generation device comprises: a compressor; an accumulator part for storing compressed air; an expander 8 driven by the compressed air from the accumulator part; a dynamo 11 mechanically connected to the expander 8; a first heat exchanger 5 for cooling the compressed air and heating heat medium by heat exchange between the compressed air supplied to the accumulator part from a compressor 4 and the heat medium; a first heat storage part for storing the heat medium heated by the first heat exchanger 5; a second heat exchanger 7 for heating compressed air and cooling heat medium by heat exchange between the compressed air supplied to the expander 8 from the accumulator part and the heat medium supplied from the first heat storage part; a second heat storage part for storing the heat medium cooled by the second heat exchanger 7 and supplying it to the first heat exchanger 5; and a third heat storage part provided separately from the first heat storage part for storing the heat medium having a higher temperature than that of the first heat storage part capable of supplying it to the second heat exchanger 7.SELECTED DRAWING: Figure 1
