根据燃烧调整工作的经验 ,锅炉只能在与设计煤种煤质变化不大的范围内运行 ,才能保证其安全性、一定的经济性和低负荷稳燃能力。煤的挥发份含量降低 5 % ,对锅炉稳燃性能的影响足以抵消船体燃烧器带来的稳燃性能的提高 ;煤中灰份提高 1 0 % ,所带来的飞灰含碳量的上升 ,难以用 According to the experience of the combustion adjustment work, the boiler can only operate within the range of little change with the design coal coal quality, in order to ensure its safety, economy and light load stability. The volatile content of coal is reduced by 5%, and the impact on the steady combustion performance of the boiler is enough to offset the steady-state combustion performance brought by the hull burner. The ash content in coal increases by 10% and the carbon content of the fly ash increases , Hard to use
