锅炉低负荷运行时其燃烧安全性和运行经济性很难统一。等离子不投运时等离子燃烧器不具备稳燃功能。低负荷时通过改变煤粉燃烧器的运行方式,通过投运具备稳燃作用的水平浓淡燃烧器,提高着火稳定性,提高主再热汽温度,减少等离子的电耗和材耗,既能提高运行安全性,又能提高经济性。 Its combustion safety and operating economy are difficult to unify when the boiler is operating at low load. The plasma burner does not have stable combustion when the plasma is not put into operation. Low load by changing the mode of operation of the pulverized coal burner, through the operation of stabilizing combustion level horizontal burner, improve the fire stability, improve the main reheat steam temperature, reduce plasma power consumption and material consumption, both to improve Operational safety, but also improve economy.
