Abstract:
Aiming at the situation that the present soot-blowing operation was unreasonable, the model of slagging monitoring around boiler furnace was built and the applicability of the monitoring model was analyzed. Through example analysis, the problems of the soot-blowing operation based on monitoring results were pointed out. A soot-blowing optimization model based on maximum heat transfer capacity per unit time of furnace was proposed, and its optimization efficiency was analyzed and compared with other models in existing studies by calculation. Finally, the soot-blowing optimization strategy was set out. The calculation results show that the model of slagging monitoring is applicable for the stable load and its results could be undulate in various loads inapplicable for soot-blowing operation. Using the average of multiple data of fouling factor to fit the curve can obtain better fitting goodness in soot-blowing optimization calculation. The soot-blowing optimization model can enhance the thermal value equivalent to 2.31 kg/min standard coal at 500 MW load of target boiler. Thus, it is more applicable for actual soot-blowing operation than other models in existing studies.
