多年的使用经验告诉我们,KZL(DZL)锅炉故障,常出在炉排上,即炉排卡死。 (1)造成该故障的主要原因①烘炉不当。烘炉时煤层过厚过集中,造成通风不良,火焰贴近炉排,致使销轴退火、变形。②排片磨损,炉排伸长。因为是前置主轴,排片磨损,炉排伸长。当排面阻力加大时,由于齿推运行造成排面皱折,从而形成阻力的恶性循环。③矸石、大块煤、煤渣增加了阻力。矸石,大块煤等硬物,卡住煤闸板增加了炉排运行负荷,使销轴弯曲,落渣,烧结的炉渣也会增加阻力。
Years of experience tells us that KZL (DZL) boiler failure, often in the grate, that grate stuck. (1) The main reason for the failure ① improper oven. When the ovens are too thick and too thick, causing poor ventilation, the flame close to the grate, resulting in pin annealing, deformation. ② row piece wear, grate elongation. Because it is the front spindle, row wear, grate elongation. When the surface resistance increases, due to the operation of the teeth caused by wrinkled surface row, thus forming a vicious circle of resistance. ③ gangue, lump coal, cinder increased resistance. Gangue, lump of coal and other hard objects, stuck coal shutters increase the grate running load, the pin bending, slag, sintering slag will increase resistance.
