Abstract

Mitsui Engineering and Shipbuilding Co, Ltd, has developed the SB15D (3MV-class) and SB60D (15 MW-class) gas turbines. The target of the development is for the use in cogeneration, but as the demand for electric power is stronger than for steam generation, high thermal efficiency was also needed. The design outline and operation results of the SB15D and design outline of the SB6D are introduced. The former is a single-shaft gas turbine and shaft end output power and thermal efficiency in design are 2.850 kW and 27.7% respectively and the test results showed good agreement with design value. The latter is also a single-shaft gas turbine with 15,400 kW and 33.1% shaft end output power and thermal efficiency.
