Fire fighting system with gas turbine engine - produces cooled inert combustion gases in water cooled afterburner chamber

摘要

The fire fighting arrangement is based on a gas turbine engine. An inert gas is used for fire fighting and this can be used for fighting fires in mines and also for preventing explosions in mines. The improved fire fighting arrangement has no superfluous components and it is hence compact without losing its efficiency. The gas turbine blows air into an afterburner chamber into which is blown fuel through a distribution. This afterburner chamber is water cooled and the cooled inert combustion gases are used for fire fighting purposes. The igniter (5) chamber (8) of the afterburner chamber (3) is connected by a pipe (9) with the high pressure zone of the engine (1). The fuel distributor outlets may face the air stream for better fuel distribution.
