基于我国的基本国情和能源政策,国内大多数的中小厂所使用的加热炉,其燃料大都以煤为主.该类加热炉能满足生产需要,投资少,建造周期短,操作容易,维修简单,所以至今仍广为使用.但其突出的问题有:①煤铁比高.②污染环境严重.③劳动条件恶劣.因此改造现有燃煤加热炉势在必行,但近年来改造工作主要还停留在改造直接燃煤加热炉上,
Based on China’s basic national conditions and energy policy, most of the domestic small and medium-sized factories use heating furnaces, most of which are mainly coal-based fuel, which can meet production needs, less investment, short construction period, easy operation and easy maintenance , So it is still widely used.But its outstanding problems are: ① coal-iron ratio. ② serious environmental pollution. ③ poor working conditions. Therefore, the transformation of existing coal-fired heating furnace is imperative, but in recent years the main transformation work Still stuck in the transformation of direct coal heating furnace,
