摘　　要：针对带双列高压加热器的超超临界机组特点,分析了双列高压加热器水侧流量不平衡对计算结果的影响。实例计算表明,采用等流量分配的加热器热平衡方法完全满足机组性能考核试验标准。对试验条件和测点布置提出了具体要求。Directing against the features of ultra - supercritical unit equipped with double - row high - pressure（HP）feed - water heaters,the influence of unbalance flow rate in the water side of double- row HP heaters upon the calculated results has been analysed. Results of calculation in concrete examples show that the adoption of thermal balance method in heaters with equal flow rate distribution can fully satisfy the test standard of performance assessment for the units, and the requirements for test conditions and arrangement of measuring points have been put forward.
