GAS-TURBINE PLANT (OPTIONS) Russian patent published in 1998 - IPC

FIELD: fire-fighting equipment. SUBSTANCE: gas-turbine plant has primary circuit incorporating inlet device, gas generator, at least one heat-transfer apparatus for conveying heat to secondary circuit, secondary- circuit fan supplying cooling air to heat-transfer apparatus, and secondary-circuit fan drive turbine. Gas generator has compressor that functions to compress working medium, combustion chamber, and compressor drive turbine. Gas-turbine plant is provided with ejector installed in primary circuit downstream of inlet device and outlet flow separator, one of them being connected to ejector. Heat-transfer apparatus used to convey heat to secondary circuit is installed downstream of gas-generator turbine. Fan drive turbine of secondary circuit is of expansion type. Heat-transfer apparatus conveying heat to secondary circuit may be optionally installed downstream of gas-generator turbine and function as contact-type working- medium cooler in the form of aerothermopressor. EFFECT: provision for producing oxygen-free cold combustion products in commercial scale for fire fighting. 3 cl, 3 dwg
