以等效焓降理论为基础 ,建立了各级加热器端差对机组经济性影响的在线计算模型 .通过该计算模型可以在线显示每级加热器端差对机组热经济性影响的程度 ,从而为运行检修人员提供了理论依据 ,对电厂节能有一定的现实意义 .
On the basis of the equivalent enthalpy drop theory, an on-line calculation model is established for the economic effects of terminal heights difference on the unit economy, and the calculation model can be used to online display the degree of influence on the unit thermal economy caused by the terminal difference of each level heater It provides a theoretical basis for the operation of maintenance personnel and has some practical significance for power plant energy conservation.
