摘　　要：在目前火电机组装机容量增加的趋势下,为保证机组的安全运行,对锅炉的稳定燃烧提出了更高要求。针对一台600 MW机组进行了氧量、一次风率和煤粉细度等单因素的燃烧优化调整试验,得出了各个因素对锅炉热效率的影响,并提出了优化运行方式。调整后的机组在节能与降耗方面效果显著,提高了运行的经济性。With the increasing installed capacity,in order to ensure the safe operation of the unit,higher requirements have been put forward to the stability of boiler combustion. Oxygen content,first stage air ratio and coal fineness have been tested specific to a 600 MW unit. Influence of various factors has been analyzed on the boiler thermal efficiency,proposing the optimized operation mode. The unit after the adjustment obviously behave well in energy saving and consumption,improving the economy performance of operation.
