Abstract

The invention discloses an efficiency improving system of a hydrogen fuel gas turbine and a control method, at least one heat exchange part is arranged, the heat exchange part is used for leading out cold energy in low-temperature hydrogen and cooling gas participating in acting in the gas turbine, and the cooled gas after heat exchange can improve the efficiency of the gas turbine; a straight-through assembly is further arranged, the low-temperature hydrogen can be controlled to circulate to exchange heat with the heat exchange part or bypass the heat exchange part to continue to circulate, and control over whether the low-temperature hydrogen exchanges heat or not is achieved; meanwhile, after the low-temperature hydrogen subjected to heat exchange absorbs heat, the temperature is increased, and when the low-temperature hydrogen enters a combustion chamber of the gas turbine, the combustion efficiency can be further improved, so that the overall efficiency of the gas turbine is improved, and the problems that the temperature of the provided hydrogen is low when high-pressure stored hydrogen or cryogenic liquid hydrogen is used as a hydrogen source; and a part of heat released by combustion needs to be absorbed when entering a combustion chamber of the gas turbine for combustion, so that the efficiency of the gas turbine is reduced.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to an efficiency improvement system and a control method of a hydrogen fuel gas turbine. Background technique [0002] Aikejun Power System Co., Ltd. discloses a heat engine, thermoelectric system and method in CN201080050795.7. A heat engine (also referred to herein alternatively as a "heat engine", "power plant", "waste heat recovery system" and "heat recovery system", "thermoelectric system") utilizes a thermodynamic cycle having a A working fluid (such as carbon dioxide) combines elements of the Rankine thermodynamic cycle to generate electricity from a wide range of heat sources. By "heat engine" or "heat engine" it is generally meant a package of equipment that performs a thermodynamic cycle; by "heat recovery system" it is generally meant that a heat engine cooperates with other equipment to transfer heat (from any source) to the engine and Remove heat from...
