Gas turbine combustion-chamber for combusting ethanol fuel

Abstract

The invention discloses a combustion chamber of a gas turbine burning ethanol fuel. The combustion chamber of the gas turbine burning ethanol fuel adopts a single tube cylinder combustion chamber structure which is formed by a combustion chamber cartridge receiver and a flame tube; an inlet of the combustion chamber is welded with the combustion chamber cartridge receiver, which is used for introducing air current; the flame tube is welded or connected by threads between an outlet and the combustion chamber cartridge receiver; liquid ethanol is supplied to the combustion chamber through an ethanol supply path, and a fuel preparation system is formed by the ethanol supply path and a rotational flow device to complete atomization and evaporation of the ethanol; an electric spark lighter is inserted in the flame tube to realize ignition startup of the ethanol combustion chamber; the whole process of ethanol combustion is completed in the flame tube so as to exhaust high temperature fuel gas from the outlet at the end of the combustion chamber; air current distribution of the combustion chamber of the gas turbine is adjusted to adapt to and exert characteristics and advantages of the ethanol fuel to the maximum extent, thereby improving combustion efficiency of the ethanol combustion and reducing pollution emission, and contributing to realizing the aims of energy conservation and environmental protection; and the combustion chamber is a key part of a micro-gas turbine with biomass fuel, which can enlarge fuel adaptability and is convenient for popularization and application.

Description

technical field [0001] The invention relates to a combustion chamber of a gas turbine, in particular to a combustion chamber of a gas turbine burning ethanol fuel. Background technique [0002] Due to the limited supply of global fossil fuel reserves and the pressure of environmental pollution, the application of biomass fuels such as ethanol and biodiesel has been strongly advocated. Among them, ethanol is a renewable energy, which can be produced by fermenting sugar and other processes, thereby reducing the dependence on non-renewable fossil fuels and benefiting the sustainable development of human beings. The application of ethanol fuel has certain strategic significance for the global response to the energy crisis. In addition, the use of biological enzyme technology and agricultural product fermentation technology can produce ethanol from various biological materials such as grain, sucrose, and fiber, which can adjust the contradiction between grain supply and demand t...

AI Technical Summary

Problems solved by technology

[0005] Most of the current gas turbines use kerosene, diesel, natural gas or syngas as fuel. Due to the difference in fuel properties, including fuel composition, calorific value and chemical ratio, there are great differences. The component technology between gas turbines using different fuels, Especially the combustion chamber, not fully universal

If the existing gas turbine combustor is used to directly burn ethanol fuel, it will lead to defects such as unstable combustion, low combustion efficiency, serious pollution emissions, and insufficient structural strength.
