FIELD: neutral gas production for fire fighting. SUBSTANCE: plant has primary-circuit inlet device, gas producer incorporating working medium compressor, combustion chamber, and compressor drive turbine, heat-transfer apparatus for conveying heat to secondary circuit, additional combustion chamber and heat-transfer apparatus, expansion-type turbine for driving secondary-circuit cooling fan, and secondary-circuit cooling for supplying heat-transfer apparatuses with cooling air. Mounted downstream of heat-transfer apparatuses are at least one additional combustion chamber, at least one additional heat-transfer apparatus, and expansion-type turbine for driving the cooling fan. EFFECT: provision for producing neutral gas on commercial scale. 1 dwg
