Problems solved by technology

At present, advanced gas turbine combustors are constantly developing towards high temperature rise and low pollution. The higher the temperature of the gas in the combustion chamber, the more conducive to the improvement of efficiency and power. However, high temperature and oxygen enrichment will lead to nitrogen oxides NO x Emissions have risen sharply

Abstract

The invention provides a fuel nozzle and a gas turbine. The fuel nozzle comprises a plurality of fuel pipe assemblies. Each fuel pipe assembly comprises a fuel pipe. A fuel channel is formed in each fuel pipe. The multiple fuel pipes are arranged in a radial shape with the axis of the fuel nozzle as the center. Each fuel pipe is provided with a fuel inlet communicating with the corresponding fuel channel. Each fuel pipe assembly is further provided with a fuel nozzle communicating with the corresponding fuel channel. The spraying direction of the fuel nozzles is forward. Rapid and uniform mixing of fuel and air can be achieved within a short time, the emission amount of NOx is reduced, the influence on the flow loss of a combustion chamber is small, and the performance of the combustion chamber can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a fuel nozzle and a gas turbine. Background technique [0002] A gas turbine is a heat engine that uses continuously flowing gas as a working medium to drive the impeller to rotate at high speed and convert the thermal energy of the fuel into mechanical work. The core components of a gas turbine include three main parts: a compressor, a combustion chamber, and a turbine. After the air is pressurized by the compressor, it enters the combustion chamber and is mixed with fuel for combustion. The hot gas generated drives the turbine to do work. As one of the three core components, the combustion chamber plays a decisive role in the performance of the entire gas turbine. At present, advanced gas turbine combustors are constantly developing towards high temperature rise and low pollution. The higher the temperature of the gas in the combustion chamber, the more conducive to the i...
