Abstract

CFD analysis has been performed to investigate flow behavior in LP exhaust hood of steam turbines and evaluate exhaust loss, which is directly related to the steam turbine performance, in it. Development of the optimum shape of LP exhaust hood has been done with an improved shape of steam guide, which plays a key role in terms of cost as well as performance. The newly developed LP exhaust hood will be applied for a large USC steam turbine having a capacity of 1,000 MW.
