摘要
本文以国内某钢铁厂为例,探讨了工业余热梯级综合利用方式问题,并研究了将钢铁厂低品位余热进行回收并用于城镇集中供热的技术途径及经济性,对国内钢铁行业内低品位余热资源的种类与规模进行了初步评估,指出钢铁厂等高耗能企业通过低品位余热供热可为大规模解决我国北方地区城镇集中供热提供一种具有循环经济属性的新型供热方式,并具有重要的节能减排、降耗增效的意义。
In this paper, it takes the low grade waste heat recovery of a certain domestic iron ＆steel plan as an example to discuss the comprehensive utilization of the industrial low grade waste heat, technological approaches, and the economy, and conducts initial analysis of types and sizes of low grade waste heat resources of iron and steel industry. It indicates that energy intensive enterprises such as iron ＆ steel plant can greatly solve the problem of district heating in Northern urban of our country through use of low grade residue heat. It is an important significant of energy conservation and emission mitigation, reducing energy use and increase of benefits.
