Abstract

The invention belongs to the technical field of heat engines, and particularly relates to a large-scale dual-fuel gas turbine for offshore power generation which comprises a gas turbine body, wherein a gas compressor impeller is rotatably arranged at one end in a tubular engine body, a gas engine impeller is rotatably arranged at the other end in the tubular engine body, a wind power impeller assembly is arranged on the surface of the end, containing the gas engine impeller, of the tubular engine body, linkage water injectors are fixedly assembled on the two sides of the bottom end of the outer wall of the wind power impeller assembly, a spiral cooling water pipe is wound around the surface, containing the gas engine impeller, of the tubular engine body, and a transmission separation assembly used for enabling the gas compressor impeller and the gas engine impeller to conduct transmission is arranged in the center of the tubular engine body. The large-scale dual-fuel gas turbine solves the problem that when operation starts, the instantaneous response effect is poor, further solves the problem that the oil consumption cost is extremely high during idling, and has the advantages that the durability and the service life of the equipment body material are prolonged, the heat emission is reduced and the like.

Description

technical field [0001] The invention belongs to the technical field of thermal engines, and in particular relates to a dual-fuel gas turbine for large-scale offshore power generation. Background technique [0002] The gas turbine is an internal combustion power machine that uses continuous flowing gas as the working medium to drive the impeller to rotate at high speed, and converts the energy of the fuel into useful work. It is a rotating impeller heat engine. The working process of the gas turbine is the simplest, called simple. cycle; in addition, there are regenerative cycles and complex cycles. The working fluid of the gas turbine comes from the atmosphere and is finally discharged to the atmosphere. It is an open cycle; in addition, there is a closed cycle in which the working fluid is used in a closed cycle; [0003] Problems existing in the prior art: [0004] Existing gas turbines are suitable for high-speed and stable operation. The efficiency is relatively low whe...
