通过现场油枪试验,分析了油压和回油压力对油枪出力及雾化质量的影响,指出循环流化床锅炉点火前一定要进行油枪试验,确定油枪的工作压力范围,同时对油枪点火的影响因素进行了分析,认为在油枪雾化质量良好的基础上,应着重关注点火风量和混合风量的调节,并通过观察火焰判断燃烧的效果。
Through the oil gun test in the field, the influence of oil pressure and oil return pressure on the oil gun output and atomization quality is analyzed. It is pointed out that the oil gun test must be conducted before the circulating fluidized bed boiler ignites to determine the working pressure range of the oil gun. The factors that affect the ignition of the oil gun are analyzed. It is believed that the adjustment of the ignition air flow and the mixed air flow should be focused on the basis of good atomization quality of the oil gun, and the effect of the combustion should be judged by observing the flame.
