The present disclosure relates to a gas turbine plant which decomposes ammonia and supplies it as fuel to a combustor of the gas turbine. The purpose of the embodiment of the present disclosure is that the gas turbine plant supplies sufficient heat to the ammonia in order to thermally decompose the ammonia effectively, and separates the residual ammonia present in the decomposition gas and supplies it to a combustor of the gas turbine.

Gas turbine plant with ammonia decomposition system

The present disclosure relates to a gas turbine plant which decomposes ammonia and supplies it as fuel to a combustor of the gas turbine. The gas turbine plant supplies sufficient heat to the ammonia in order to thermally decompose the ammonia effectively, and separates the residual ammonia present in the decomposition gas and supplies it to a combustor of the gas turbine.

Disclosed herein is a combined power generation system that includes a heat recovery steam generator configured to recover exhaust heat from a gas turbine to produce steam and including a high-pressure superheater and a reheater, a steam turbine operated by receiving the produced steam and including a high-pressure turbine, a medium-pressure turbine, and a low-pressure turbine, a condenser installed under the low-pressure turbine to condense steam, a high-pressure steam line for supplying the high-pressure turbine with the steam produced by the high-pressure superheater, a medium-pressure steam line for supplying the medium-pressure turbine with the steam that has passed through the high-pressure turbine, a high-pressure bypass line connected from the high-pressure steam line to the medium-pressure steam line, a reheat steam bypass line connected from downstream of the medium-pressure steam line to the condenser, and an additional high-pressure bypass line connected from the high-pressure steam line to the condenser.
