Abstract

The invention relates to the technical field of gas turbines and steam turbines, in particular to an infrared low-temperature combustion device and an infrared low-temperature combustion method of a dual working medium combined-cycle turbine. The device and the method are suitable for power supplies of big or small walking machinery and seat stand machinery on land routes and water routes. The device is characterized in that an infrared net cover is arranged in front of an oil nozzle in the position of an inlet of a combustion chamber. According to the method, flames are smashed by the infrared net cover and come into full contact with air, so as to quickly and fully combust; the combustion lag time of fuel is shortened, so that energy is concentrically released within short time; high temperature of a combustion area is increased; the incandescent spot among the layers of the flames is eliminated; the temperature of the initial combustion of gas is regulated and controlled by utilizing a diffluent second working medium; and generating conditions of harmful gas are eradicated, so as to prevent the harmful gas from being generated.

Description

technical field [0001] The invention relates to the technical fields of gas turbines and steam turbines, namely an infrared low-temperature combustion device and method for a dual-mass combined cycle turbine. The dual-mass combined cycle turbine aims at eliminating thermal damage, improving thermal efficiency, and reducing self-consumption power of gas turbines. It is suitable for the power source of large and small walking machines and table machines on land and water. Background technique [0002] In the existing technology, the gas turbine has low thermal efficiency, serious thermal damage, large self-consumption power, high requirements for material selection, high manufacturing cost, and limited practical application. A. Thermal efficiency: 18~38%. B. Working temperature: 1340~1430℃ (gas index). C. The concept of improving thermal efficiency is: to increase the working temperature as much as possible, and to increase the flow rate of the working medium by increasing ...
