摘　　要：以火电机组轴封渗漏及利用系统为研究对象,在定热量等效焓降法的理论基础上,经过严密的数学分析与推导,得出了火电机组轴封渗漏及利用系统的矩阵分析计算模型。该模型采用矩阵形式表示,计算模型与热力系统结构之间具有一一对应的关系。应用检验表明,计算简捷、通用性强,可应用于不同类型机组的分析和机组的多种不同工况。更适用于作为计算机处理的数学模型,对实现火电机组的节能降耗具有重要的理论意义。With the labyrinth leakage and reclaim system for the coal-fired power unit research object, on the basis of the heat equivalent enthalpy drop method the theory, after rigorous mathematical analysis and derivation, educing the matrix model of account and analysis of the labyrinth leakage and reclaim system for the coal-fired power unit. The type in a matrix format, between the model structure and thermal systems is one-to-one relationship. Application testing show that the calculation is simple and high universality, can be applied to the analysis of different types of units and a variety of different units working conditions. More applicable to a computer with mathematical model,the achievement of the Power Unit energy consumption of great theoretical significance.
