减温器的类型与应用

Type and Application of Desuperheater

减温器的功能是将过热蒸汽转化为饱和蒸汽或者过热度较低的蒸汽,通过减温水与过热蒸汽的热交换,降低过热蒸汽温度,最终达到热平衡。通过相关参数的计算,选择合适的减温器。介绍了常见减温器的类型,分析了影响减温效果的因素,提出了减温器在选型及安装过程中应注意的问题,对减温器的更好了解和使用有一定的帮助。

The function of desuperheater is to convert superheated steam into saturated steam or low temperature superheated steam.The temperature of superheated steam is reduced through heat exchange between warm water and superheated steam to reach heat balance eventually.Suitable desuperheater is selected by calculating relative parameters.Problems about selection and installation of desuperheater are presented with introduction of types of desuperheater and evaluation of factors affecting temperature reduction, which help to understand and use it better.
