Design and Operating Results of 145 MW Low Caloric Gas Fired Combined Cycle Power Plant for Chiba Works of Kawasaki Steel Corporation

摘要

Recently there is a strong requirement in steel industries to utilize the low caloric by-product gas for high efficiency and large capacity gas turbines, since rapid progress is being made in thermal efficiency by the adoption of higher firing temperature technology to gas turbines. The MHI has delivered a 145 MW gas turbine combined cycle power plant, firing low caloric by-product gas (1,000 kcal/Nm(3)) generated in the steel manufacturing processes, to Chiba Works of Kawasaki Steel Corporation in December 1987. The paper reports the design features and the operating results of this plant, which has been working very satisfactorily from the start of operation.
