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.

A vertical type once-through heat recovery steam generator (HRSG) capable of improving operational stability during rapid startup and lifetime of a steam turbine while reducing environmental pollution caused by emissions, and a combined power generation system including the HRSG are provided. The HRSG includes a medium-pressure section including a medium-pressure side desuperheater installed at the rear of a medium-pressure superheater to lower the temperature of the steam supplied to a medium-pressure steam turbine, and a high-pressure section including a high-pressure side desuperheater installed at the rear of a high-pressure superheater to lower the temperature of the steam supplied to a high-pressure steam turbine.

A scrubber includes: a first body for burning toxic gas introduced into a combustion chamber, using a flame generated by a cathode electrode and an anode electrode, and auxiliary gases including hydrogen and oxygen; a second body which is connected with the first body and serves to induce complete combustion of the burned toxic gas in an in-chamber and indirectly cool the toxic gas; and an electrolysis unit serving to produce hydrogen and oxygen by electrolysis and supply the produced hydrogen and oxygen as auxiliary gases to the first body. In the scrubber, a high combustion rate can be achieved even at relatively low power by a combination of high energy, obtained by the combustion of hydrogen and oxygen, with combustion heat caused by plasma, and toxic gas can be more efficiently treated by increasing treatment temperature.
