Abstract

Abstract: In this paper, the technical specifications of the 1 350 MW steam turbine in the Shenergy Anhui Pingshan Power Plant Phase II Project are introduced, such as the high and low positioned layouts, double shaftings and double reheat cycles. Particularly, the high positioned turbine train consists of one VHP cylinder and one HP cylinder, and the low positioned turbine train consists of two IP cylinders and three LP cylinders. Then the optimized selection for the turbine unit capacity and turbine module arrangement is presented and the comparative analysis is also carried out on different turbine module arrangements. Moreover, the selection and related optimization for the steam parameters of the turbine is explored. At last, the axial fixed points of the turbine trains and the structure characteristics of turbine modules and valves are put forward.

Key words: steam turbine, 1 350 MW, ultra-supercritical parameter, double reheat cycles, high and low positioned turbine layout
