阶梯式自密封技术在烧结环冷机余热发电上的应用
|
摘要
烧结环冷机台车与烟罩之间的密封问题是影响烧结余热发电的关键因素之一,解决密封问题能够减少冷风直接漏入高温废气中,提高余热发电效率。韶钢烧结余热发电项目采用阶梯式自密封技术进行升级改造,取得了良好的效果。
Sealing between the cooler trolley and flue hood is one of the key factors influencing sinter waste heat power generating; and solution of the sealing problem can reduce cool air directly leaking into high temperature flue gas and increase power generating efficiency. The sinter waste heat power generating project of Shaogang adopts step self-sealing technology in upgrading transformation, which has produced good results.
