摘要
通过对现行相关标准中加热炉热效率计算方法的分析,讨论将入炉冷空气显热计入入炉总能量对加热炉热效率计算结果的影响,探讨更能真实反映加热炉能源利用效果的热平衡分析模型及计算方法,并讨论在进行节能效益预期中两种方法的优缺点。
By analyzing the computation methods of thermal efficiency of heating furnace suggested by the current standard, when the sensible heat of input cool air is regarded to be one part of total input energy, the variation of thermal efficiency of heating furnace is discussed. The thermal equilibrium model,which can really reflect utilization results of energy of heating furnace, is presented, and the advantages and disadvantages of two methods in the expectation of benefits of energy saving are compared.
