摘要
钢铁生产是高温作业.为达到可持续发展的要求,应在物料方面实行再循环,尽力实现废弃物"零排放",在能源方面尽可能减少能量消耗.热化学法回收冶金生产过程的余热,有可能实现能量转化过程熵的梯次递增原则,减少火用损失,达到能量利用的高效率.此外,把余热热能转化为化学能,有利于远距离输送,改善国民经济的工业生态链.本文对冶金生产余热的热化学回收进行了初步探讨.
The steel production is a high temperature technology.For the purpose of the sustainable development,the recycle and proper reuse of materials should be put into practice to reach the 'zero waste' target.Moreover,the decrease of the energy consumption will be continued.The thermochemical recovery of the waste heat during steelmaking manufacture would minimize the exergy loss of the energy transformation,it obeys the cascade principle of the entropy increment.The chemical energy source is easily transported in a long distance way,so it is helpful for the inter-process linkage among different industries.The thermochemical recovery of high temperature waste of steel production is discussed in this paper.
