摘　　要：余热发电技术在钢铁企业中得到了广泛应用。钢厂主要利用烧结、焦化和炼钢生产工序中产生的废气、烟气和蒸汽等能源,并将其通过一定工艺转换为电能。余热发电相对于传统发电方式具有显著的优势,不仅能够充分实现二次能源的利用,提高能源利用率,降低损耗,而且能够显著节约成本,获得更高的经济效益。此外,余热发电还可以提高生产效率,从而使生态环境得到有效保护,有害气体的排放量也会随之减少。这在推动中国的节能降耗、环境维护以及持久发展策略上起着关键的作用。该文详细描绘了干熄焦烧结余热发电工程中福建三钢闽光股份有限公司(以下简称“福建三钢”)所采用的凝汽式余热发电机的独特技术,以及通过复合余热能源实现的高效发电,并对该工程的具体运作及成功案例进行了说明。Waste heat power generation technology has been widely applied in the steel industry.Steel plants primarily utilize energy from waste gases,flue gases,and steam produced during processes such as sintering,coking,and steelmaking,converting them into electrical energy through specific processes.Compared to traditional power generation methods,waste heat power generation offers significant advantages.It not only maximizes the use of secondary energy,improves energy efficiency,and reduces losses but also significantly saves costs and yields higher economic benefits.Furthermore,waste heat power generation enhances production efficiency,which in turn effectively protects the ecological environment and reduces the emission of harmful gases.This plays a crucial role in advancing China's energy conservation,environmental protection,and sustainable development strategies.This paper provides a detailed description of the unique technology employed by Sansteel Minguang Co.,Ltd.,Fujian.(hereinafter referred to as"Fujian Sansteel")in their dry quenching sintering waste heat power generation project.It highlights the use of steam turbine waste heat generators and the efficient power generation achieved through composite waste heat energy.The paper also discusses the specific operations and successful case studies of this project.
