随着我国机械工业的飞跃发展,机械制造工厂中必不可缺的动力部门之一——鍋爐房,也日益得到扩展。在新工厂中要建立新的鍋爐房;在旧工厂中由于生产的不断发展,也要扩建旧有的鍋爐房或另建新的鍋炉房。在旧式鍋爐房中,燃料(煤)的供应及灰渣的排除,绝大部分是依靠人力。在耗煤量不大的情况下,劳动力不足的现象还不太显著。但在生产日益发展的 With the rapid development of China’s machinery industry, boiler room, one of the indispensable power units in the machinery manufacturing plant, has also been expanded. In the new factory, a new boiler room is to be built; in the old factory, due to the continuous development of production, it is necessary to expand the old boiler room or build a new boiler room. In the old boiler room, the supply of fuel (coal) and the removal of ash are largely dependent on manpower. In the case of low coal consumption, the phenomenon of labor shortage is not yet significant. But in the growing production
