能源问题是我国存在的实际问题,为人们所关注.目前我国中、小型工厂仍然以煤为主要能源,手烧式燃煤加热炉仍在被广泛使用.虽然有少数工厂采用煤气炉加热,但还处在不断模索经验和不断改造中.也有的大型企业把连续生产的燃煤加热炉由手烧式改为机械化加煤,效果很好.这样不仅节约能源,减轻工人劳动强度,而且还能减少环境污染.但对中、小型工厂,尤其对工件批量小的厂家,如果用机械化加煤,不仅耗资大,从经济效益讲也很不适宜.所以多数中、小型工厂目前仍然采用 At present, China’s small and medium-sized factories still use coal as their major energy source, and hand-fired coal-fired reheating furnaces are still widely used.Although a few factories use gas furnaces for heating, Still in the constant experience and continuous reforming.Other large enterprises to the continuous production of coal-fired heating furnace from manual to mechanical coal, the effect is very good.This will not only save energy, reduce labor intensity, but also Reduce the environmental pollution.However, for medium and small factories, especially for small batch manufacturers, if using mechanized coal, it is not only expensive but also economically not suitable, so most small and medium sized factories are still using
