Research and Application on the Key Technology of 800 t/h Circulating Fluidized Bed Boiler
Based on the design conditions of an 800 t/h high-temperature and ultra-high pressure circulating fluidized bed boiler in a certain petrochemical enterprise,in order to improve the reliability and economy of the boiler,key technologies such as in furnace anti-wear technology,cooling separator outlet flue technology,and equal pressure secondary air box technology were deeply studied.The results show that the use of anti wear technology in the furnace effectively alleviates the wear phenomenon of the water-cooled wall,separator,and tail heating surface,and significantly improves the reliability of the boiler.By adopting the cooling type separator outlet flue technology,the amount of castable used is reduced,and the heat dissipation loss of the boiler is reduced.The use of equal pressure secondary air box technology greatly improves the uniformity of air distribution and combustion.Since its operation,the boiler has been in stable operation,with operating parameters superior to design requirements,and excellent reliability and economy.
