Depending on how one defined performance optimization, the term could include cycle modifications and support systems that are external to the gas turbine core. Some examples are: • cycle modifications (which may also include, but are not limited to, inlet cooling systems, that are discussed under “Design Development”) • engine condition monitoring systems • life cycle counters/ assessment In the interests of space, these topics are not discussed here but they are exhaustively covered in the author’s book on Gas Turbines. As discussed in the section on design development, performance optimization is frequently attained by maximizing the power available using modifications to the base core. This allows the OEM to use proven technology that has long emerged from prototype growing pains, to fulfill a broader mandate in terms of power requirements and other operational needs. A case in point, Siemens’ SGT-700 (29MW) is an uprated SGT-600 (24MW), which then fills a broader range of applications. Fig. 66. SGT-700 Gas Turbine - 29MW (Improved power output and efficiency over the SGT-600) (Source: Siemens Westinghouse) The SGT-700 has simple cycle shaft output of 29.1 MW and a thermal efficiency of 36% at base load on gas. This two-shaft machine can be used for both power generation and mechanical drive in both combined cycle and cogeneration applications. As a skid-mounted package with single-lift capacity and standard anti-corrosion materials and coatings, the SGT-700 is also suitable for offshore applications. The updated machine has full dry low- emission (DLE) capability. It can operate on both gas and liquid fuels with on-line switch- over between fuels. To optimize performance, the SGT-700 power turbine is equipped with advanced profile blades that improve gas flow. Its overall design ensures easy service access to the combustor and burners. The revised 11-stage compressor produces a higher pressure ratio and an increase in mass flow through the engine. This results in greater power output and higher efficiency. Direct drive of pipeline or process compressor is provided for by the free high-speed power turbine, eliminating the need for a gearbox. The digital control unit is based on the proven design of the SGT-600. An application case for the SGT-700 illustrates an example of extending the application of a basic gas turbine core (in this case the SGT-600) design. We noted in the section on design development, and the Mitsubishi case study (see Case Study 2) which listed several variations on the same GT core that additional power was added with essentially the same gas turbine core, with the addition of design features (for instance steam cooling instead of air cooling in certain hot section areas). Frequently, these developments result from a customer’s request: “I really could use another “x” MW in that plant, if you can make that happen” or “I’d rather have a slightly larger version of your “y” model rather than two of the “z” model, as I only have “w” amount of space and I can run the larger “y” at base load anyway, most of the time”. This “core growth” design is really an extension of design development work, as any such design modification has to be full load tested. Some air or steam leaks may not show up at 60% load, but may appear at close to 100% load. So the OEM goes through the expense of rigorous testing to minimize the risk of warranty-period costs. 55PDF Image | GAS TURBINES IN SIMPLE CYCLE COMBINED CYCLE APPLICATIONS
