Abstract

The invention discloses a micro gas turbine fuel oil system and a control method thereof. A dual-oil-way oil supply manner is used for respectively supplying oil to a starting fuel oil nozzle and a main fuel oil nozzle; the combustion stability, the combustion efficiency and the uniformity of the temperature of the combustion chamber outlet can be greatly improved. According to the micro gas turbine fuel oil system, an onboard fuel oil pump, an acceleration regulating device and a starting electromagnetic valve are adopted, so that the structure simplicity of the fuel oil system can be greatlyimproved; a rotation speed and height compensation device is adopted, the environmental adaptability of the fuel oil system can be greatly improved; a starting cleaning valve is adopted, the servicelife of the starting fuel oil nozzle and the fuel oil system can be greatly prolonged; the gas turbine fuel oil system is of great significance to being simple and lightweight in structure, easy to maintain and high in reliability.

Description

technical field [0001] The invention relates to the field of gas turbine fuel system, in particular, to a micro gas turbine fuel system and a control method thereof. Background technique [0002] Micro gas turbine is a kind of newly developed small thermal engine, its stand-alone power ranges from 25 to 300kW, and it is mainly composed of compressor, combustion chamber, turbine, reducer, fuel system, lubricating oil system and so on. The micro gas turbine generating set has a series of advantages such as high efficiency, low noise, low pollution, small weight, small volume, and multiple integrated expansion. [0003] The gas turbine fuel system is an important system component of the gas turbine. It provides the fuel required by the gas turbine according to the law, ensures the normal start of the gas turbine within the working range and maintains the constant speed of the gas turbine under any working conditions, and provides power to the outside world. The existing fuel s...
