电厂回热系统递推计算方法研究

STUDY OF RECURRENCE CALCULATION WAY OF REGENERATIVE SYSTEM AT POWER PLANTS

本文在电厂蒸汽循环的循环函数式“加热单元”理论的基础上，依据加热器进出口疏水量之间的关系，提出了一种新的分析火电厂回热系统热经济性的递推计算法．该方法简化了计算公式，更方便于编制通用性较强的计算机程序，并通过实例证明该递推模型是正确的．

Based on the theories on the heating unit in the circulation function for the calculation of steam circulation at power plants,and taking into consideration of the relations of the drains at the input and output of the heater,this paper proposes a new recurrence formula for the calculation and assessment of the economy of the regenerative system of coal fired power plants.The proposed method has simplified the conventional formulae of calculation so as to make the programming of a more general purposed package of software easier,and proved the correctness of the recurrence model through examples.
