摘要
通过分析分隔屏过热器的水动力特性和热偏差情况 ,提出了分隔屏过热器的改造方案。改造前后的热力性能数据表明 ,改造后分隔屏过热器的流量分配系数、危险点管壁计算温度比改造前更趋平稳。图5表
Following the analysis of the hydrodynamical characteristics and the state of temperature divagations observable sectional divided platen superheaters, a reconstruction proposal is being presented. A comparison of thermal property data, before and after reconstruction, shows that the flow distribution coefficients and the calculated temperature, at the latter's critical spots have leveled off.
