随着国民经济和科学技术的发展,无烟煤不但是民用燃料,而且也是工业生产中愈来愈重要的原燃料。过去许多要求块状燃料的工艺设备,如煤气发生炉、电石炉、石灰窑、铸造化铁,都把焦炭作为主要能源,而今都可以使用无烟煤进行生产。现在,无烟煤是扩大生产和节约焦炭的重要燃料来源。无烟煤用在各 With the development of the national economy and science and technology, anthracite is not only a civilian fuel, but also an increasingly important raw fuel in industrial production. In the past, many of the process equipment requiring lump fuel, such as gas furnaces, calcium carbide furnaces, lime kilns, and cast iron, all used coke as their main source of energy, and anthracite coal can now be produced. Anthracite is now an important fuel source for expanding production and saving coke. Anthracite used in each
