Abstract

APPLICATION OF BOX-BEHNKEN DESIGN FOR THE OPTIMIZATION OF STEAM TURBINE EFFICIENCY

Eyere Emagbetere*, Festus I. Ashiedu, Olusegun D. Samuel and Modestus O. Okwu

ABSTRACT

In order to contribute to the development of a steam turbine locally, a ten (10) megawatt steam turbine was designed for power generation. MATLAB was used to develop simulation program for a two stage turbine with re-heater and regeneration Rankine cycle. Box–Behnken response surface methodology with three-level-three factor central composite design was used to investigate the effects of re-heat pressure, first feed pressure and second first water pressure on the efficiency of the turbine. Re-heat pressure between 0.5-3.0 MPa, first feed pressure of 0.70- 1.20 MPa and second first water pressure of 0.1-0.5 MPa were employed in the simulation experiment. Optimization technique predicted 42.3% the efficiency of 10 MW steam turbine designed.
