摘要
基于有效热降理论的热力系统热经济性计算通用矩阵方程,能有效克服热经济性矩阵分析方法需要联立其它方程才能求解热力系统最终热经济性指标的缺陷,并将其应用到回热系统中。得出在机组负荷偏离额定负荷运行时,系统效率的变化情况。研究和分析加热器的经济性指标与运行工况的关系,更好地掌握加热器系统特征和提高系统的运行水平,是提高机组的经济性和安全性的关键。
A matrix equation for the thermal economic calculation in thermo dynamic system based on the equivalent heat drop theory which overcomes effectively the problem of other jumped - up thermal economic matrix equation requiring other simultaneous equations on calculating the final thermal economic target and applied in regenerative feed -water system. When aircrew′s load deviates from rated condition, the change of systematic efficiency can be obtained. The purpose of researching economic index and operation operating mode the heater is to grasp the systematic characteristic of the heater, imorove the systematic operation level and economy and security of the aircrew.
