Problems solved by technology

[0004] The efficiency of a gas turbine is generally closely related to the pressure ratio and combustion temperature. When the pressure ratio is too high or the combustion temperature is low, the system efficiency will decrease instead.
Increasing the pressure ratio is actually beneficial to reduce the exhaust temperature, but it increases the overall irreversible loss, thereby reducing the system efficiency. In addition, increasing the pressure ratio also greatly increases the size of the equipment and reduces the technical and economic performance.
In addition, appropriately lowering the combustion temperature is conducive to reducing the heat resistance requirements for materials, but when the temperature is lowered, the system efficiency is also greatly reduced, making the gas turbine have to work under high temperature conditions

Abstract

The invention provides a gas power device. The gas power device comprises an air supply machine, rotating joints, a turbine, a gas pipe, an oil pipe and a rotating shaft; an air outlet of the air supply machine communicates with a gas inlet of the gas pipe after penetrating through the first rotating joint through a pipe; an external oil supply pipeline communicates with an oil inlet of the oil pipe after passing through the first rotating joint; an oil outlet of the oil pipe communicates with a pipeline of the gas pipe; and a gas outlet of the gas pipe communicates with an intake port of theturbine through a pipe after passing through the second rotating joint. The invention further provides a gas power method; oil enters the oil pipe; air enters the air pipe through the air supply machine; and after the oil and the air are mixed for combustion, power is outwards output after pressure energy is released from the turbine. The system structure is simple; and a simple pipeline is used for replacing a complicated impeller runner, so that higher efficiency is achieved under the condition of high pressure ratio, and the higher pressure ratio can be adopted.

Description

technical field [0001] The invention relates to the technical field of energy and power, in particular to a gas power device and method. Background technique [0002] Gas turbine is a widely used internal combustion power machine with the characteristics of high efficiency and compact structure. A gas turbine is mainly composed of three major components: a compressor, a combustion chamber, and a turbine. The cycle composed of these three components is called a simple cycle, and most gas turbines generally use a simple cycle. [0003] When the gas turbine is working, the compressor inhales air from the outside atmosphere. After adiabatic compression, the temperature and pressure of the air rise, and then the compressed air is sent into the combustion chamber, where it absorbs the heat released by the combustion of fuel in the combustion chamber and becomes a high-temperature and high-pressure gas. The high-temperature and high-pressure gas then enters the turbine and expands...
