小型旋转油炉具有结构简单、操作方便、生产率高、加热质量好等优点,故一般工厂均乐于采用.但是它仍存在着不足的地方,即加料口处炉气始终处于较大的正压状态,不论压缩空气的压力大小,炉口火焰向四周喷射,加上炉口上段外壁的温度很高,劳动条件仍较差,有待进一步改善. Small rotary oil furnace has the advantages of simple structure, convenient operation, high productivity, good heating quality and so on, so the general factory is willing to adopt it, but it still has some shortcomings, that is, the feeding gas at the inlet is always in a relatively positive pressure Regardless of the pressure of the compressed air, the flame at the mouth of the furnace is sprayed to the periphery. In addition, the temperature of the outer wall of the upper section of the furnace mouth is very high, and the working conditions are still poor and need to be further improved.
