| Abstract: | According to operational characteristic of 1 000 MW ultra-supercritical octagonal tangential boiler, this paper adopts measures such as changing air distribution way, reducing primary air parameter and proper oxygen content control to carry out optimization and adjustment testing for boiler combustion. Optimization testing result indicates that power consumption of the forced draught blower, induced draft fan and primary fan and NOx emission mass concentration are both reduced after combustion optimization. Meanwhile, the overall economy of the boiler is improved and safety allowance of the tube panel of heating surface is increased, too. |
