Problems solved by technology

However, the waste gas emitted during the process of chemical energy power generation has caused air pollution and ecological damage
On the other hand, the conversion efficiency from chemical energy to electrical energy has not been greatly improved, especially in small generators. Due to the restriction of engine efficiency, the conversion efficiency of electrical energy is usually only about 30%, and unburned Exhaust gas HC, CO and harmful gas NOx, etc., pollute the environment
In addition, due to the existence of the centrifugal compressor wheel of the traditional gas turbine, the power consumption of supercharging is additionally increased, resulting in low energy conversion efficiency of the gas turbine

Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, the micro hybrid oxy-combustion gas turbine generator described in this embodiment is composed of seven systems, including fuel supply system, oxygen-enriched air supply system, combustion work system, control system, power generation system, and energy recovery system and lubricant system.

[0024] The fuel supply system includes a fuel tank 12, a fuel delivery pump 13 and a controllable flow valve 14 connected in sequence along the fuel delivery direction, wherein the output end of the controllable flow valve 14 is connected to an input end of the jet valve 30, and the jet valve 30 The other input end is connected to the pure oxygen output port of the pure oxygen generator 19 in the oxygen-enriched air supply system, and the output end of the jet valve 30 is connected to the fuel input end of the combustion chamber 17 in the combustion power system. In order to make the controllable flow valve 14 control the actual fuel injection v...

Embodiment 2

[0037] Embodiment 2: as figure 2 As shown, the structure of this embodiment is basically the same as that of Embodiment 1 (using the fuel jet to absorb pure oxygen and then mix and dilute it with air in the combustion chamber). At the entrance, there is a premixing chamber 16 which communicates with the air inlet of the combustion chamber 17 and the pure oxygen output port of the pure oxygen generator 19. At the same time, the corresponding pipeline is adjusted as follows: the output end of the controllable flow valve 14 is directly connected to the combustion chamber 17, an output port of the controllable proportional valve 20 is communicated with the air inlet of the premix chamber 16, and the other output port is still communicated with the pure oxygen generator 19, and the pure oxygen produced by the pure oxygen generator 19 is connected with the The air output by the controllable proportional valve 20 is mixed and diluted in the premix chamber 16 to form oxygen-enriched ...

Description

technical field [0001] The invention relates to a gas turbine generator, in particular to a micro-mixed oxygen-enriched combustion gas turbine generator, which is mainly suitable for small gas turbine generators. Background technique [0002] Electric energy has become one of the most widely used forms of energy due to the convenience of transmission and conversion. As a secondary energy source, electric energy has a variety of ways to obtain it. Among them, obtaining electrical energy from chemical energy is currently the most widely used method of obtaining electrical energy. However, the waste gas emitted in the process of chemical energy power generation has caused air pollution and ecological damage. On the other hand, the conversion efficiency from chemical energy to electrical energy has not been greatly improved, especially in small generators. Due to the restriction of engine efficiency, the conversion efficiency of electrical energy is usually only about 30%, and...
