据有关资料报导,我国工业锅炉目前已达三十多万台,其中手烧炉比重很大,大都是块煤和粉煤一起燃烧,耗能大,烟尘多。如果采用国外将块煤和粉煤筛选分离,手烧炉燃烧块煤,这样每台锅炉的效率就可提高20％。那么,全国现有十万台以上的快装锅炉每年至少为国家节约标准煤二千万吨。 According to relevant information, the number of industrial boilers in our country has reached more than 300,000 at present, of which the proportion of hand-burners is very large. Most of them are burned with lump coal and pulverized coal, which consumes large amounts of energy and smoke. If the use of foreign lump coal and pulverized coal screening separation, hand burning lump coal burning, so that each boiler efficiency can be increased by 20%. Well, there are at present more than 100,000 quick-acting boilers nationwide that save at least 20 million tons of standard coal each year.
