Hydrogen fueled gas turbine engine

Claim 1

A hydrogen fueled gas turbine engine comprising an air compressor (3) for compressing air, an outer housing (2) having at one end an inlet port (4) connected to the air compressor (3) and at the other end an outlet port (18), an inner housing (5) coaxially supported in the outer housing (2), a hydrogen gas jet nozzle (6) fixedly mounted to the inner housing (5) so as to jet hydrogen gas (7) into the interior of the inner housing (5), a water spray jet nozzle (13) for spraying water sprays (14) into the interior of the inner housing (5), and at least one ignition plug (17) for igniting the hydrogen gas, characterized in that said inner housing (5) is formed at its peripheral surface with a multiplicity of circumferentially equispaced apertures (8) for admitting the compressed air into the interior of the inner housing (5), that a semi-spherical member (10) is coaxially supported in the inner housing (5) so as to define therewithin a combustion zone (11) upsteam of the semi-spherical member (10) and a mixing zone (12) downstream of the combustion zone (11) and is formed at its peripheral surface with a multiplicity of circumferentially equispaced apertures (15), that said water spray jet nozzle (13) is fixedly mounted to the apex of the semi-spherical member (10) to spray the water sprays (14) into the mixing zone (12), and that the water sprays (14) are instantly vaporized to steam by igniting the hydrogen gas (7) thereby to utilize the combustion/explosion energy of the hydrogen gas (7) and the steam energy generated from the vaporization of the water sprays (14) in combination to obtain mechanical dynamic energy.
