Research On Engineering Application Of SNCR Technology For CFB Boilers

This thesis is based on the author's experience on CFB boiler engineering work.Through the analysis on the SNCR technical's engineering application on CFB boiler,the author discussed the design pricinple of engineering design and equipments selection. Author make good use of combination of calculation formula, model theory with engineering design data, project experience and relevant chart, data sheet. The author compared some different type SNCR systems adopted in project with each other to find out their advantage and disadvantage.The emphasis of the thesis is the research on the design of the aqueous ammonia SNCR system used on CFB boiler. The author analyzed the key point of engineering and equipment selection and modeling methods and steps. Via both the theory and engineering experience study, we can get the conclusion that the SNCR system adopted on CFB boiler with compact separator is capacity to achieve high efficient NOx removal.
