摘要
电厂实际运行中,汽轮机背压对热经济性的影响非常大。以汽轮机和凝汽器变工况理论为基础,结合EEDM方程,用MATLAB编程,能够准确、快速地得出背压变化与机组热经济性的微增关系曲线,对机组运行和节能分析都具有重要意义。
Turbine exhaust steam pressure （back pressure） affects thermal economy greatly in power plant practical operation. In the paper,based on the variable condition theories of steam turbine and condenser,combined EEDM equation, and used MATLAB to program, a slight increased relationship between condensing steam exhaust pressure change and thermal economy is concluded exactly and fast. It is significant for unit operation and energy-saving analysis.
