余热利用技术在首钢的应用

首钢在新建首秦、迁钢和京唐三地钢厂过程,通过余热直接利用、余热发电等技术应用,不断提高余热利用水平.在粗钢产量实现3154万t的同时,首钢2010年吨钢综合能耗降至618 kgce/t.在介绍副产煤气和蒸汽的回收利用现状基础上,介绍了轧钢系统采取换热器、蓄热式燃烧和热装热送等技术应用情况；重点阐述了余热发电情况如TRT...

APPLICATION OF WASTE HEAT RECOVERY TECHNOLOGY IN SHOUGANG

Utilization efficiency is improved by technology application such as waste heat direct-utilization and power generation in the process of three new-built steel plants such as SHOUQIN,QIANGANG and JINGTANG.Energy consumption per-ton of SHOUGANG is 618kgce.t-1 with its crude steel output reaching 31.540 million tons in 2010.On the base of introducing recovery and utilization of by-product gas and steam,technology applications such as heat exchanger,regenerative combustion,hot charge rolling in steel rolling are illustrated,waste heat power generation such as TRT,CDQ and BFG is illuminated on stress.It shows that the developing direction of waste heat recovery and utilization is large-scale and high-efficiency,and it has the important function to solve power in the steel enterprises,and the difficulty of waste heat recovery in SHOUGANG is the recovery of lower temperature waste heat and BF molten slag.
