FIELD: power engineering. ^ SUBSTANCE: intermediate cooler is arranged in gas flow between two compressors or two groups of compressor stages furnished with heat exchange surfaces to compress gas, while extra cooler is arranged downstream of second compressor. To utilise off gas coming onto said coolers, heat exchange surfaces of intermediate and extra coolers are incorporated with steam generator to make said surfaces communicated with feed pump 40, 59 of steam generator 9. ^ EFFECT: heat recover of off gas of two compressors or two groups of gas compression compressors. ^ 8 cl, 2 dwg |
