摘要
阐述控制循环锅炉水动力计算方法的基本原理和水循环安全性的设计标准;对计算的主要内容,包括炉膛的吸热量分配、回路划分、节流圈选用、Runback工况,锅筒蒸汽携带率、以及循环泵的NPSH等予以说明,并简要介绍计算过程及其与自然循环水动力计算方法的比较。
Philosophy of controlled circulation boiler hydrodynamic calculation method and water circulation safety design criteria are described. The author gives out main coverage of the calculation including furnace heat absorption capacity distribution, loop division, selection of throttle orifice, Runback working conditions, drum steam carrying rate as well as NPSH of circulation pump etc. Calculating procedure and comparison of natural circulation hydrodynamic calculation methods are briefly introduced.
