Verification Full Load Test Of 900 T/H (1,980,000 LB/H) Large Mechanical Drive Steam Turbine For ASU Up To 200 MW (268,000 HP) Based On Principle Of High Scale Model Similarity.

Abstract

In 2009, the authors designed a compressor drive steam turbine for air separation units (ASU) application up to 200 MW (268,000 hp), using large 500 mm (19.7 inch) blade rows, which have a low-pressure (LP) flow capacity of up to 900t/h (1,980,000 lb/h). These 500 mm (19.7 inch) blade rows were tested under actual load conditions between August and September 2008 at the authors’ shop, based on the principle of high scale model similarity. In conclusion, excellent results were obtained and the reliability of the blade rows was verified.
