Study On Cost Management Model For Supply Chain Based On The Meager Profit Environment

Coal combustion is one of the major reasons for serious air pollution all over the country with rapid development of economics. Plenty of coal combustion led to NOx emitting and disaster for the environment. The thesis is mainly about how to control the NOx emitting in the process of its formation and after its formation. Foster Wheeler CFB Boiler has fuel flexibility, capacity to burn low grade fuels, no complex chemical cleaning systems, and meets strict emission regulations easily. Introduce the theory of SNCR system, the reducer, and the temperature for the reduction etc. for the system. The author compares the deference between SNCR and SCR, describe the calculation formula for NOx emitting. Through the project Jiahua 3×410t/h CFB boiler as an example, make the conclusion that SNCR system in CFB boiler can catch the requirement of NOx emitting standard published by the government.
