机组轴封系统热经济性向量分析法及应用

A Vector-based Approach to the Thermal Economy of the Unit's Shaft Seal System and its Application

在轴封系统热经济性矩阵分析模型的基础上,提出热交换向量概念,由此推导出了轴封系统热经济性向量分析模型,其与热力系统结构一一对应。应用表明,该模型计算简捷、通用性强、易于理解、编程,适用于不同火电机组的轴封系统。

Based on the matrix analysis approach to the shaft seal system＇ s thermal economy, the paper puts forward the heat exchange vector and deduces the model of vector analysis approach to the shaft seal system＇ s thermal economy which is corresponding to the thermal system＇ s structure. Application indicates that the model whose calculation forthright and commonality powerful, especially suits for understanding and computer programming. So the model applies to any thermal power units of the shaft seal system.
