摘要 分析了热平衡分析方法和平衡分析方法的局限性,由此引出能级分析方法,介绍能级分析方法在分析能量合理利用过程中的重要性。从能量的"品质"方面讨论钢铁企业余热回收利用系统中供能与用能双方的合理匹配问题,同时讨论了不同级别余热资源的利用方式的合理性。最后结合转炉烟气余热回收实例,探讨转炉余热蒸汽回收的合理利用方式,为钢铁企业余热资源的回收与合理利用提供参考。 The limitations of thermal equilibrium and exergy balance methods were investigated.The energy level analysis method and its importance during analyzing the reasonable utilization of energy were also introduced.In respect of energy quality,the reasonable matching of energy supply and energy use of waste heat recovery system at iron and steel enterprises were discussed with the method of energy level analysis.The reasonable recycling methods of waste heat with different energy levels were also discussed.Finally,as an example,recovery of converter flue gas heat and reasonable utilization of the steam were discussed,which could be a reference for the recovery and rational utilization of waste heat for the iron and steel enterprises.
