根据我国当前能源政策,在今后一个时期内煤是主要能源。因此工业用加热炉应尽可能以煤作燃料。但当某些锻件要求加热端部时,用煤作燃料的传统的缝式加热炉(以下简称旧炉)由于存在加热效率低、速度慢、耗煤量大、三冒(冒火、冒烟、冒灰)现象严重、工人劳动条件恶劣等弊病,故其使用与推广受到限制。为根治旧炉上述弊病,我们设计了一种新的双缝式燃煤加热炉(以下简称新炉),并于一 According to China’s current energy policy, coal is the main source of energy in the coming period. Therefore, industrial furnaces should be as coal as possible fuel. However, when some forgings are required to heat the ends, conventional seam furnaces (hereinafter referred to as “old furnaces”) that use coal as fuel have the disadvantages of low heating efficiency, slow speed, large coal consumption, Take the ash) serious problems, poor working conditions and other workers ills, so its use and promotion is limited. In order to cure the aforementioned defects of the old furnace, we designed a new double-seam coal-fired heating furnace (hereinafter referred to as the new furnace)
