A few years ago, Sulzer introduced two new gas turbines to the market, namely the 9-MW single-shaft type 7 and split-shaft type S 7 machines. Twenty-six units have been delivered to date, and over 100,000 field operating hours accumulated. The positive experience with this machine has allowed an uprating to 10 MW. Changes in the structure of the market, particularly the importance of platform installations, have caused Sulzer to redesign the machine’s auxiliaries, which have been, to a great extent, integrated into the gas turbine package. Flexibility in the application of the machine, easy maintainability, and ruggedness were maintained by reducing the required space to less than half the ground area. The main purpose of this paper is to describe the improved turbine of today. The prototype is briefly described and operating experience is listed. The main part of the paper is devoted to a comprehensive description of the redesigned gas turbine package and its new auxiliary system.
