FIELD: power industry.
SUBSTANCE: heat recovery steam generating unit is the unit based on Rankine organic cycle with the electric generator, and the intermediate loop for utilisation of heat of exhaust gases of the gas turbine is the closed loop with diathermic oil which incorporates two heat exchangers and the circulation pump; through one heat exchanger the line of removal of exhaust gases of the gas turbine passes, and through the second heat exchanger - the line of the unit based on Rankine organic cycle; the internal consumers of electric energy of the gas-distributing station are connected to the electric generator unit based on Rankine organic cycle.
EFFECT: invention allows to increase efficiency of combustion in natural gas at the main gas-distributing stations due to obtaining of additional electric energy by conversion of heat of exhaust gases in the unit based on Rankine organic cycle and decrease of material costs for supply by electric power of internal consumers of gas-distributing stations.
