Abstract

A hydrogen fuelled gas turbine which includes a combustion chamber having a steam inlet, an oxygen inlet, a hydrogen inlet, and an outlet. A compressor is provided. The steam inlet is connected to the compressor such that the compressor provides steam as a working fluid. The hydrogen inlet is connected to a source of hydrogen gas, whereby hydrogen gas serves as a fuel for combustion. The oxygen inlet is connected to a source of oxygen gas, whereby oxygen is supplied to oxidize the hydrogen fuel. An igniter is disposed within the combustion chamber whereby the hydrogen/oxygen mixture is explosively ignited. The products of combustion combine with the steam and rapidly expand out through the outlet of the combustion chamber. A turbine is provided having an inlet, an outlet and a rotatable member disposed in a flow path between the inlet and the outlet. The inlet of the turbine is connected to the outlet of the combustion cheer such that expanding products of combustion and steam exert a force to rotate the rotatable member when passing from the inlet to the outlet. The compressor has an inlet coupled with the outlet of the turbine whereby steam from the outlet of the turbine is recycled. The compressor has a plurality of water injectors adapted for connection to a water source whereby water is injected into the steam such that the water draws heat from the steam as it vaporizes thereby triggering a physical volume reduction.
