1. A gas turbine plant with an ammonia decomposition system, the gas turbine plant comprising:
a storage tank configured to store liquid ammonia;
a supply pump configured to supply the liquid ammonia of the storage tank;
a preheater configured to preheat the liquid ammonia supplied by the supply pump;
a vaporizer configured to vaporize the liquid ammonia preheated by the preheater;
a superheater configured to superheat the gaseous ammonia vaporized by the vaporizer;
a decomposition reactor configured to thermally decompose the gaseous ammonia superheated by the superheater;
a separator configured to separate residual ammonia from the decomposition gas decomposed by the decomposition reactor;
a first combustor configured to generate combustion gas in such a way as to supply heat to the decomposition reactor; and
a heat exchanger configured to recover the heat from the combustion gas that has passed through the decomposition reactor,
wherein synthesis gas consisting of hydrogen and nitrogen with the residual ammonia removed by the separator is supplied to a second combustor of a gas turbine.
