摘　　要：在锅炉设计及控制系统选型的阶段,选取合理的过热器区段焓增、蛇形管内径、蒸汽流速及控制策略,需兼顾各种因素对动态特性的影响。利用单相区段动态特性的计算方法,计算出1197t/h控制循环燃油/天然气锅炉的高温过热器的动态特性,通过系统仿真试验,提出了对原设计的过热器汽温控制方案的改进方法,供热工控制工程师根据工程要求在现场调试时参考。During boiler design and the selection of control-system stage, all factors related with the effect of dynamic characteristics shall be considered when select reasonable SH section enthalpy increase, I. D. of coiles, steam velocity and control philosophy. This paper computed 1197t/h controlled circulation oil/gas firing boiler high-temperature superheater's dynamic characteristics via singlephase zone dynamic characteristics computing method. And it set forth improvement on original SH steam temperature control option, which is a reference for I&C engineers per engineering request during their stay on site.
