摘　　要：为研究额定工况条件下直流蒸汽发生器各热工参数(一次侧平均温度、给水温度、负荷和蒸汽压力)发生设计偏离对其稳态特性的影响,开展了针对直流蒸汽发生器原型设计典型栅元的热工水力实验。实验工况范围:一次侧平均温度297~304℃,负荷100%FP~104%FP(FP表示满功率),蒸汽压力4.0~5.8 MPa,给水温度138~152℃。实验结果表明,各热工参数偏离主要影响蒸汽发生器出口蒸汽温度、换热功率和二次侧压降;一次侧平均温度发生设计偏离对蒸汽温度的影响最大;在各热工参数同时发生设计偏离条件下,出口蒸汽温度随蒸汽压力增加而减小。In order to study the influence of design deviation of thermal parameters(average temperature of primary side,feed water temperature,load and steam pressure)on the steady-state characteristics of once-through steam generator(OTSG)under rated conditions,the thermalhydraulic experiment of typical cells for prototype design of OTSG is carried out.The experimental conditions are as follows:the average temperature of primary side is 297-304℃,the load is 100%FP-104%FP(full power),the steam pressure is 4.0-5.8 MPa,and the feed water temperature is 138-152℃.The experimental results show that the deviation of thermal parameters mainly affects the outlet steam temperature,heat transfer power and secondary side pressure drop of OTSG.The design deviation of the average temperature of primary side has the greatest influence on the steam temperature.The outlet steam temperature decreases with the increase of steam pressure under the condition that the design deviation of each thermal parameter occurs at the same time.
