Test plan research and development for improved efficiency, small steam turbine, Project No. 1380, Phase II, Revision A

Abstract

Northern Research and Engineering Corporation together with Terry Steam Turbine Corporation is currently engaged in a development program aimed at demonstrating that a family of high efficiency radial inflow steam turbines (RIT) can be developed to meet the demands of the small (500 to 5000 hp) steam turbine market, such that significant market penetration, hence significant savings in the nation's use of energy, will result. The program is being conducted in two phases. During Phase I, recently completed, the market for small steam turbines was examined and the family of radial inflow turbines best suited to penetrate the market was identified. Phase II is concerned with the testing of small steam turbines to meet market requirements. The tests specified include component testing, mechanical rotating testing, and performance testing. The component and mechanical rotating tests are designed to assure the integrity of the machine prior to performance testing and verify the results of engineering analyses employed in its design. The performance tests are meant to demonstrate the predicted performance which has been the rationale for this program. The purpose, requirements, procedures and completion schedule for each test are described. (LCL)
