Summary: | The present invention relates to a fire suppressing apparatus and more specifically to a gas generator to produce a large quantity of inert gas of low oxygen concentration within a short period of time. The present invention also relates to vehicles equipped with such gas generator to suppress fire.
Disclosed in an inert gas generator to produce a large quantity of inert gas within a short period of time. The inert gas generator comprises: a gas turbine consisting of a starter motor, compressor, combustor and turbine body; an afterburner being connected to an exit of the gas turbine to re-burn gas burned in the combustor and being equipped with a flame stabilizer; a cooling chamber being equipped with spray nozzles to eject water to decrease gas temperature in the afterburner exit; an evaporator set to further cool the gas-steam mixture from the afterburner; a cooling chamber and spray nozzles; an exhaust nozzle to guide the direction of the inert gas-steam mixture of low temperature and oxygen content; and a controller for controlling the starter motor, the fuel pump and combustor. The inert gas generator mounted on a movable vehicle can promptly suppress the fire occurred in various places with least amount cost possible. |
