燃气蒸汽联合循环余热锅炉能效分析的矩阵模型

Gas-steam Combined Cycle Heat Recovery Boiler Energy Efficiency Matrix Model Analysis

燃气蒸汽联合循环机组作为一种环保性好、效率高、调峰性好的机组已成为我国发电机组中不可或缺的组成部分,在未来仍有很大的发展潜力。但是,目前针对于燃气——蒸汽联合循环电站的热经济性分析一般只使用常规热平衡法和火用分析方法两种方法。而本文中使用了矩阵分析法,导出了三压再热型的燃气——蒸汽联合循环机组热力系统分析计算方法。此方法物理意义明确且通用性为强,数据易处理,结果易分析。为进一步用矩阵理论研究燃气——蒸汽联合循环机组的节能降耗奠定了基础。

The gas-steam combined cycle unit as an environmentally friendly,high efficiency,good peaking generating unit has become an integral part of the group,the future is still great potential for development. However,currently targeted for gas-thermal analysis method using two methods of economic analysis steam combined cycle power plants generally use only conventional heat balance method and fire. The paper uses a matrix analysis derived three pressure reheat type of gas- steam combined cycle unit thermal system analysis and calculation methods. This method is a clear physical meaning and versatility for strong,easy to handle data,the result is easy to analyze. and lay the foundation for further studying energy consumption of gas- steam combined cycle unit by matrix theory.
