FIELD: engines and pumps.
SUBSTANCE: heat-recovery gas turbine power plant incorporates two stages, a consecutively mounted engine, fan, compressor, combustion chamber, low- and high-pressure turbines linked to the fan and compressor, heat exchanger and a free air turbine. The circular heat exchanger is arranged in the second stage. The heat exchanger gas space communicates with the gas exhauster arranged nearby the engine intake device. The said exhauster houses a heat exchanger-gasifier communicating, on one side, via the fuel line with the liquefied natural gas pump and, on the other side, with the combustion chamber nozzles. The free air turbine is also arranged in the gas turbine second stage.
EFFECT: gas turbine higher efficiency and reliability.
