This invention discloses a low NO X A hydrogen-ammonia fusion micro gas turbine includes a combustion chamber with several secondary air inlets on its wall. These secondary air inlets are used to introduce a portion of compressed air and a first-pass liquid ammonia fuel into the combustion chamber. Within the combustion chamber, a pyrolysis chamber with a pyrolysis gas outlet is located near the turbine end. This pyrolysis chamber contains a catalyst and is supplied with a second-pass liquid ammonia fuel. The second-pass liquid ammonia fuel is pyrolyzed under the heat energy of the combustion chamber and the action of the catalyst. The resulting pyrolysis gas enters the combustion chamber through the pyrolysis gas outlet for combustion. This invention utilizes the high-temperature flue gas generated in the combustion chamber as a heat source to achieve catalytic pyrolysis of ammonia within the gas turbine combustion chamber, producing a hydrogen-rich mixture, which is then introduced into the combustion chamber as a combustion aid to stabilize the ammonia combustion flame and reduce NO. X While emitting pollutants, energy is utilized in a tiered manner.
