Description of a 9000 HP Single Shaft Gas Turbine

Low first cost and little need for maintenance assure the industrial gas turbine an important place for many applications where the lower thermal efficiency as compared with other prime movers is not a decisive factor. The simplicity of the gas turbine finds its best expression in the compact integrated single shaft design featuring a single compressor-turbine rotor supported in two bearings, the whole including the combustion system being contained in a common casing structure. The recognized need for simplicity together with reliability has been the main consideration in the design of the unit presented in the following description. At present, an intensive test program is under way and it is expected that the new Clark gas turbine will soon be ready for installation.
