把煤变成可燃性气体对锻件进行加热,这是一种先进的加热方式。煤气炉和反射炉相比,它具有很多优点:炉温稳定,加热速度快,质量好。对改善工人的劳动条件比较理想,在减少烟尘对环境的污染方面效果也很显著,是今后的发展方向。但一般煤气炉只能做间歇运行,每班都必须清渣、铺渣、生火、添加燃料煤,操作比较麻烦。由于这种煤气炉是间歇运行,因而不能长时间稳定的供应煤气,气化过程,不易控制。在发生了局部煤层烧穿时,还需要打开炉盖进行调整,使煤气大量逸出。这不仅对司炉有毒害,而且对锻件加热也有影响。为此,根据现存问题我们进行了改
Turning coal into a flammable gas heats forgings, an advanced heating method. Compared with the reverberatory furnace gas stove, it has many advantages: stable temperature, heating speed, good quality. To improve the working conditions of workers is ideal, in reducing the environmental pollution caused by smoke and dust is also very significant effect, is the future direction of development. However, the general gas stove can only do intermittent operation, each class must be cleared slag, shop slag, fire, add fuel coal, the operation is too much trouble. Because of this gas stove is intermittent operation, which can not be a long period of stable supply of gas, gasification process, not easy to control. In the event of a partial burning through the coal seam, you also need to open the lid to adjust, so that a large number of gas escape. This is not only poisonous to the stoker but also affects the heating of the forgings. For this reason, we have changed according to the existing problems
