FIELD: natural-gas burning power stations. SUBSTANCE: power plant that burns natural gas whose gage pressure is reduced downstream of distribution gas line in throttling devices has expansion-type gas turbine inserted between high- and low- pressure pipelines and connected to electric generator. Installed downstream of turbine are condensate separator and circulating pump inserted in condensate pipeline as well as gas phase and condensate heaters with heating medium supply lines. Mixer inserted in high-pressure pipeline at expansion turbine inlet is connected to separator on one side through gas phase pipeline with gas compressor inserted in this line and connected to expansion-type gas turbine; on other side mixer is connected to condensate pipeline with condensate flow regulator inserted in this line. Such mechanical design provides for better utilization of natural gas potential energy and extends plant control range at varying gas consumption by users. EFFECT: improved operating efficiency of plant. 1 dwg
