| Abstract: | This paper analyzes the causes leading to the high heat consumption and poor efficiency of the imported-type 300 MW condensing steam turbine with dual casings and dual exhausts. 3-dimensional technology, including the meridian contracting type governing stage and back-bent twisted blades technique,is used to renovated the HP-IP turbine flow-passage, in order to raise the units＇ economic efficiency and reliability. The application of this technology to the Jiangxi Fengcheng Power Plant 4 × 300 MW units can provide a useful reference for other similar units to increase their capacity and reduce consumption. |
