Problems solved by technology

[0004] In addition, for liquid fuels with a flash point greater than or equal to 60°C, during the start-up or shutdown phase of the micro-combustion engine, due to the drop in the temperature of the combustion chamber, the atomization of the fuel in the combustion chamber will be insufficient, and then it will appear when it is mixed with air and combusted. Insufficient combustion, resulting in black smoke from the exhaust end of the micro-turbine
This situation will not only cause waste of fuel, but also leave residues (such as powder) of incomplete combustion of fuel on the inner wall of the combustion chamber

Abstract

The invention discloses a fuel supply system with a dual-fuel system. The fuel supply system comprises the dual-fuel system, a buffer tank, a nozzle and an evaporation pipe. The buffer tank is arranged on a fuel supply main path, or is arranged on a fuel supply branch path where the evaporation pipe is located, or is arranged on a fuel supply branch path where the nozzle is located. The dual-fuel system comprises a first fuel supply branch used for supplying first fuel, a second fuel supply branch used for supplying second fuel and a three-way pipe fitting, wherein the three-way pipe fitting communicates with the first fuel supply branch, the second fuel supply branch and the fuel supply main path. The invention further discloses a micro gas turbine with the fuel supply system. According to the fuel supply system, the buffer tank is arranged in the fuel supply main path or branch path so that the successful switching of the ignition stage can be realized. In addition, double types of liquid fuel are supported by the fuel supply system, the fuel selection application range of the micro gas turbine is expanded, the fuel can be fully burnt, residues which are not fully burnt cannot be left on the inner wall of a combustion chamber, and the fuel supply system has the high application value.

Description

technical field [0001] The invention relates to a fuel supply system with a dual-fuel system and a micro gas turbine, belonging to the technical field of gas turbines. Background technique [0002] The micro-combustion engine uses continuously 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, which mainly includes three major components: a compressor, a combustion chamber and a turbine. , the compressor inhales air from the external atmosphere, and compresses it to pressurize it, and at the same time, the air temperature increases accordingly; the compressed air is sent to the combustion chamber and mixed with the injected fuel to generate high-temperature and high-pressure gas; The flat expansion works, and the turbine is driven to drive the compressor and the external load rotor to rotate together at a high speed, which realizes the partial conversion...
