北京能源总消费量大约为2000～2500万吨标煤。工业部门能源终端消费量一直保持在70％左右,约1400万吨。其中冶金工业,化学工业,机械工业及建材工业等四个部门约用能源1150万吨标煤。占工业总消费量的80％左右。所以工业炉窑的节能工作应以这四个部门为主要对象,提高它们的热效率,其他部门兼顾之。这里所说的工业炉(窑)指的是热风炉,轧钢前的连续加热炉,锻造炉和热处理炉,各种隧道窑,玻璃熔炼炉,反射炉,各种有色金属加热炉,各种工业电阻加热炉等。只要能抓紧这些炉(窑)的技术改造,使它们热效率达
Beijing’s total energy consumption is about 2000 ~ 25 million tons of standard coal. The energy consumption in the industrial sector has remained at about 70%, about 14 million tons. Among them, four departments, metallurgy industry, chemical industry, machinery industry and building materials industry, used approximately 11.5 million tons of standard coal. Accounting for about 80% of total industrial consumption. Therefore, the energy-saving work of industrial kilns should focus on these four departments and improve their thermal efficiency, taking into account other departments. The industrial furnace (kiln) as used herein means a hot blast stove, a continuous heating furnace before rolling, a forging furnace and a heat treatment furnace, various tunnel kilns, a glass melting furnace, a reflection furnace, various non-ferrous metal heating furnaces, Resistance furnace and so on. As long as these furnaces (kilns) can be restructured so that they are thermally efficient
