【摘要】 在某重型机械厂大型加热炉热能平衡测试的基础上应用热力学第二定律的(火用)分析方法对用能状况进行了有效性分析和计算,建立了(火用)平衡表。在分析讨论了燃烧温度、反应初始条件、传热等对(火用)损失的影响以后,提出了节能的方向和途径。更多还原

【Abstract】 The present analysis is here presented in three parts . In the first part isgiven a calculation of the total exergy loss of the combustion process . The second part of this analysis deals with the exergy loss resulting from the irreversibility of the combustion process as predicted by the second law of thermodynamics . The last part of the paper suggests on general measures to be taken aimed at saving of energy for the furnace .更多还原
