Embodiment Construction

[0011] exist figure 1 Among them, the special combustion system 1 and the Yao-type II screw-shell turbine engine 2 form a Yao-type II low-grade gas screw-shell turbine engine. The special combustion system 1 is composed of a gas storage tank 3 , a flashback preventer 4 , an air-fuel ratio regulator 5 , a gas supercharger 6 and an electric heating mesh combustion chamber 7 . The Yao type II screw-shell turbine engine 2 is made up of a turbine 8, a turbine shaft 9, a first-stage booster pump wheel 10, a second-stage booster pump wheel 11, a guide wheel 12 and an expansion chamber housing 13. The turbine 8 is connected to the first-stage booster pump wheel 10, the second-stage booster pump wheel 11 and the generator 13: the guide wheel 12 is fixedly installed in the middle of the first-stage booster pump wheel 10 and the second-stage booster pump wheel 11 The inner wall of the expansion chamber housing 14 . There is a bell-shaped fairing 15 above the second-stage booster pump w...

Abstract

A Yao type-2 turbine engine and a special combustion system form a Yao type-2 low grade fuel gas externally heated turbine engine. The turbine engine is composed of a turbine, a turbine shaft, a two-level booster pump wheel and an expansion chamber shell. An air inlet support is arranged at the lower part of the expansion chamber shell, and the upper part of the air inlet is provided with a two-level booster pump wheel fixedly arranged on the turbine shaft. The special combustion system is composed of a gas storage tank, an anti backfire device, an air-fuel delivery ratio adjuster, a gas booster and a combustion chamber with electric heating wire mesh; an outlet of the combustion system is communicated with the lower end of the expansion chamber shell of a spiral casing turbine engine or is communicated with a heat exchange turbine engine connected with a low thermal resistance of the expansion chamber shell, and the hot air generated in the special combustion system heats up and expands gas inside the expansion chamber shell, is converted into high grade mechanical energy and is output. In the invention, harmful gases generated in the process of mining and refining by enterprises such as coal mines and oil fields are converted into output power or electric energy with very low cost, thus not only eliminating pollution but also saving precious energy.

Description

Technical field [0001] The invention relates to a Yao type II low-grade gas external heating turbine engine. Background technique [0002] Low-grade fuel, the present invention only refers to a certain combustible gas or multiple combustible gases, mixed with other gases, and the proportion is so small that it has lost its commercial application value, so low-grade fuel is thin, scattered and unstable. Low-grade fuels are generally difficult to ignite, and even if ignited, they will automatically extinguish: even if they continue to burn, the temperature is very low. In the mining and refining process of coal mines, oil fields and other enterprises, if these low-grade fuels are directly discharged into the atmosphere, air pollution will be generated, and purification treatment will consume costs. Contents of the invention [0003] The purpose of the present invention is to provide Yao type II low-grade gas externally heated turbine engine. [0004] The technical solutio...
