【摘要】 余热蒸汽升值利用是钢铁企业解决余热资源回收不足及蒸汽放散的有效措施。本文给出了余热蒸汽合理利用程度的指标(λ),指出了提高余热蒸汽动力装置热效率的措施。并以热力学第二定律为基础,建议钢铁企业的余热蒸汽实施就地发电的形式,同时,分析了余热蒸汽发电的节能效果。更多还原

【Abstract】 The appreciate use of afterheat steam is an effective measure to solve the problem of deficiency in recovering afterheat resource for steel and iron enterprises.This article present the index(λ) as describing reasonable utilization extent of afterheat steam,and put forward some measures which can enhance the thermal efficiency of power equipment of afterheat steam.On the basis of second law of thermodynamics,this article suggest that steel and iron enterprises can generate electricity on the spot by using afterheat steam.Meanwhile,the article analyze the effect of energy saving of electricity generating from afterheat steam.更多还原
