USE OF THE ABSORPTION LITHIUM BROMIDE REFRIGERATING MACHINE FOR INCREASE IN OVERALL PERFORMANCE OF COMPRESSED-AIR POWER STATION

Abstract

The scheme of compressed-air power plant with use, during recession of electric loading, the absorption lithium bromide refrigerating machinefor additional cooling of compressed air in an aftercooler in front of the air accumulator is offered. The technical and economic analysis of possible variants of change in structure and duration of operation of the compressor and turbine equipment of compressed-air power plant in connection with additional decrease in temperature of compressed air when using absorption lithium bromide refrigerating machineby 10 – 20 ºС is carried out. The variant of introduction of absorption lithium bromide refrigerating machine in the scheme of compressed-air power plant at which profiles of the compressor and gas turbine don't change and changes the duration of their work, it appears more effective.
