节约能源与防止污染是我国四化建设必须解决好的重大问题,也是我们铸造工作者的重要任务。砂型烘炉对铸造行业来说,既是能耗较大的设备,又是烟尘较大的污染源,迫切需要研究其节能与消烟的可行办法。我们为探索解决这个问题的途径,研制了简易煤气发生炉,利用工业窑炉不能使用的劣质碎煤作原料,转变为煤气后供砂型烘炉作燃料, To save energy and prevent pollution is a major issue that must be solved in building the four modernizations in our country. It is also an important task for our foundry workers. Sand casting furnace for the casting industry, both energy-intensive equipment, but also a larger source of pollution smoke, there is an urgent need to study its energy-saving and smoke feasible approach. To explore ways to solve this problem, we developed a simple gas furnace, the use of industrial furnaces can not be used as a poor raw coal, converted into gas for sand furnace for fuel,
