Abstract


With the continued development of the economy, China's energy and environmental issues are becoming more prominent. The face of the average energy utilization is low, the current situation of serious environmental pollution, various forms of clean coal power generation technology in China has been a lot of development, in which the core gas turbine combined cycle power generation system is the most respected. Polygeneration system for gasification gas and pyrolysis gas, syngas gasification gas rich in carbon, coke oven gas (pyrolysis gas), hydrogen-rich characteristics combined total of the whole technology of gasification gas and coke oven gas, The gasification gas CO and coke oven gas CH 4 converted into synthesis gas. The components and parameters of the crude gas in the cogeneration system with the changes in the working conditions of the changes. In order to ensure that the output power of the power generation system is stable products, enter the gross calorific value of the gas turbine fuel must be deployed depending on the operating conditions, and fuel gas must be guaranteed to be stable, adequate, low pollution combustion. Therefore, it is necessary to study the basic combustion characteristics of the crude gas. This paper studied the characteristics of gaseous fuel combustion and diffusion combustion and premixed combustion affect the flame propagation speed factors from flame structure, the two forms are compared. On this basis, by the chain reaction analysis, there is explained the main component of the crude gas hydrogen, carbon monoxide, methane combustion reaction mechanism. And determining the gas component, pressure, temperature and other parameters of the experimental studies. OF component according to the crude gas to the combustion chamber and burner design calculations, for a reasonable selection in accordance with the calculation result of the analytical instruments, thus completing the experimental system can be suitable for the crude gas basic combustion characteristics of the diffusion combustion Design. Has a simple structure, easy to manufacture, easy removal of independent design Longti combustion chamber, the combustion chamber height and diameter than the freedom transformation can be easily realized, thus greatly improving the flexibility and stability of the combustion system. Experiments in different excess air ratio, combustion characteristics of the crude gas. Experimental results show that the excess air ratio distribution of the change on the combustion temperature of the crude gas and products greater impact, the use of a reasonable excess space factor conducive to improve the combustion temperature of the crude gas, to promote complete combustion of the crude gas. Finally, of the problems and deficiencies found in the experiment, respectively, from the gas source, the bench body and the measuring system of the experimental system proposed recommendations for improvement the next stage basic combustion characteristics outlook crude gas.
