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 IC engineers per engineering request during their stay on site.
