钢铁工业能耗占全国能耗的13一14％,是我国耗能高、浪费大的重点.因此,在节约能耗和回收二次能源上是大有潜力的.下面谈谈热风炉能源节约和能源合理利用的几点意见. 一、我国的热风炉基本上还是考贝式内燃热风炉,不论从结构上、燃烧器的型式上和耐火材质上都比较陈旧,已经不能满足高风温的要求.因此,在热风炉的改造中设计和采用合理的型式,减少能源的消耗,获得较高的热效率是相当重要的。采用顶燃或改造型内燃都是可取的,但从投资省、热效率高方面来说顶燃优于后者. 二、在合理选择炉型的基础上,加强炉墙和热风管道的绝热,在绝热砖与钢壳之间再敷
Steel industry, energy consumption accounts for 13-14% of the national energy consumption, is China’s high energy consumption, waste a big focus, therefore, energy conservation and recovery of secondary energy is great potential. Here to talk about the stove energy saving And the rational use of energy opinions.A, China’s stove is basically a test-style internal combustion stove, regardless of the structure, the type of burner and refractory materials are relatively old, can not meet the high wind temperature Therefore, it is very important to design and adopt a reasonable type of stove in order to reduce energy consumption and obtain higher thermal efficiency. It is advisable to adopt top combustion or reforming internal combustion, but the top combustion is superior to the latter in terms of investment and high thermal efficiency.Secondly, on the basis of reasonable selection of furnace type, Between the adiabatic brick and steel shell and then deposited
