Abstract

Abstract:

The early domestic 300MW impulse steam turbine has poor economical efficiency and hidden safety troubles; so it is necessary to reform its flow

passage to overcome its defects. Using the threedimensional thermal design technology, the flow passage of the turbine in a power plant was reformed. After

the reformation, the heat consumption, the safety function and other indexes of the unit achieve or close to the designed value. The result of this paper

provides reference for reformation of flow passage of similar units.

Key words: steam turbine, reformation of flow passage, impulse
