Design Concept

The SGT-800 is a single shaft machine with fifteen compressor stages. The first three stages have variable geometry. To minimize leakage over the blade tips, abradable seals are applied to stages four to fifteen. The three stage turbine is built as one module for ease of maintenance and is bolted to the compressor shaft. Turbine stator flanges are air cooled to reduce running clearances and improve efficiency. Its overall design ensures easy service access to the combustor and burners. The cold end of the gas turbine is connected to the generator via speed reduction reducing turbine speed from 6,600 rpm down to 1,500/1,800 rpm. The machine has full Dry Low Emissions (DLE) capability, providing low NOx levels. It can operate on both gas and liquid fuels with on-line switchover between fuels.

Power Generation Package

The SGT-800 is available as a skidmounted package with single-lift capacity of the main machinery skid. It is easily transported, installed and maintained at site. The package incorporates the gas turbine, gearbox, generator and all mechanical  auxiliary systems are mounted on a single underbase. Turbine controls, generator control panel, motor control center for package motors and variable speed drive for starter motor are normally also package-mounted.
