在以煤代油、压缩烧油、堵住烧油漏洞的压力下,不少机械工厂的锻造加热炉都正在或将要停止烧油,改为烧煤或煤气。本文从讨论发生炉煤气的优缺点入手,从提高工业炉综合利用水平着眼,对小型煤气发生站的设计和使用,对充分利用废热的金属热交换器,对各类节能的新型烧嘴及新型耐火材 Under the pressure of using coal instead of oil, compressing oil and plugging oil loopholes, many forging furnaces of machinery factories are or will stop burning oil instead of burning coal or gas. This article starts from discussing the advantages and disadvantages of producer gas. From the perspective of improving the comprehensive utilization of industrial furnaces, the design and application of small-scale gas generation stations are put forward. For metal heat exchangers that make full use of waste heat, Refractory
