摘　　要：吹灰是提高锅炉运行安全与经济性的重要措施之一,合理的优化吹灰会提高机组的经济性。以国内某亚临界300MW燃煤锅炉作为研究对象,用等效焓降法对优化吹灰与常规吹灰经济性作了分析。运行数据结果表明,优化吹灰可有效的提高锅炉效率,降低主、再热蒸汽的温度波动,提高了锅炉运行的经济性。Sootblowing is one of the important measures to improve operation safety and economy,a reasonable blowing will raise the efficiency of unit.For a domestic subcritical 300 MW unit,the economics between optimal blowing and normal blowing are investigated based on the enthalpy drop method.The result indicated that optimal blowing not only can increase the efficiency,but also reduce the temperature of superheated steam and reheated steam, with a improving efficiency of boiler operation.
