Problems solved by technology

Hydrogen can be obtained by decomposing fuel ammonia without having to purchase it separately, but ammonia decomposition is usually carried out under low pressure and catalyst conditions, requiring separate ammonia decomposition equipment, which is inconvenient

Abstract

The invention discloses an ammonia fuel pre-decomposition-regeneration cooling combustor, a gas turbine and an operating method. A first ammonia fuel channel and a second ammonia fuel channel are arranged in the air channel of the combustion chamber, and liquid ammonia fuel can be fed in respectively. A fuel heat exchanger is arranged on the side close to the nozzle group in the air channel and communicates with the nozzle group. An ammonia decomposition channel is arranged in the flame cylinder, the inlet end is connected with the second ammonia fuel channel, and the outlet end is connected with the fuel heat exchanger. The first ammonia fuel passage is arranged near one end of the nozzle group, and its outlet end is connected with the fuel heat exchanger. A part of the liquid ammonia fuel is decomposed into a hydrogen-containing mixed gas through the ammonia decomposition channel, and a part of the liquid ammonia fuel is used to cool the hydrogen-containing mixed gas, thereby realizing ammonia pre-decomposition and fuel regeneration cooling. The invention has the advantages of strengthening the cooling of the wall surface of the combustion chamber, the flame tube, and the flame, vaporizing ammonia and thermally decomposing it into hydrogen to improve combustion efficiency, broaden the boundary of low-load operation, and reduce nitrogen oxide emissions.

Description

technical field [0001] The invention relates to an ammonia fuel pre-decomposition-regeneration cooling combustion chamber, a gas turbine and an operation method, belonging to the technical field of gas turbines. Background technique [0002] The flame temperature in the combustion chamber of the gas turbine is very high, and the combustion chamber wall and the flame tube need to be cooled, and this problem is even more serious in the combustion chamber burning ammonia. The rich-quench-lean combustion method used to control nitrogen oxide emissions has an optimal equivalence ratio and cannot be adjusted at will. At this time, the temperature of the combustion area at the head of the combustion chamber is very high, which is the area with the highest temperature in the combustion chamber; In order to increase the flame speed of ammonia, hydrogen-doped combustion is usually required, which further increases the temperature of the combustion zone. On the other hand, the inlet a...
