Abstract:
An inert gas generator for fire suppressing comprising:a gas turbine, which comprises a starter motor, a combustor being connected to a fuel pump burn air compressed in the compressor, and a turbine body installed at an exit of the combustor to generate power through expansion process; an afterburner being connected and installed at an exit of the turbine body, being connected to the compressor by a bleed off line to be provided with a portion of air extracted from the compressor for fuel atomizing and to re-burn gas burned in the combustor, and supplied through the turbine body, and being provided with a flame stabilizer to stabilize flame produced by re-burning of the gas burned in the combustor; a cooling chamber enclosing the afterburner to take combustion heat in the afterburner and to inject water through spray nozzles into gas re-burned in the afterburner to decrease temperature of the re-burned gas; an evaporator being installed at an exit of the cooling chamber for further cooling the re-burned gas which is already been cooled by the cooling chamber and the spray nozzles; an exhaust nozzle for guiding exhaust gas which has been cooled in the evaporator to a fire area; and a controller for controlling the starter motor, the fuel pump, the combustor, and the afterburner.
