Application of quadratic regression orthogonal design to optimization surface heating for control wet steam condensation flow in nozzle

Autor: Xu Han, Jiandong Guan, Qiuliang Zhu, Zhonghe Han

Publikováno v: Case Studies in Thermal Engineering, Vol 34, Iss , Pp 101987- (2022)

The condensed flow of wet steam in the low-pressure cylinder of a steam turbine will affect the safety and economy of the unit's operation. Therefore, it is necessary to reduce the influence of the wet steam on the turbine blades after condensation.
