The Siemens SGT-400 industrial gas turbine is a combination of 25 years of design experience and solutions from the SGT 100 and SGT 300 models, as well as the latest combustion technology. As a result, the SGT-400 provides reliable power generation for a wide variety of applications. In industry, it is used for both power generation and mechanical drive.
The GTU is equipped with a combustion chamber with dry suppression of nitrogen oxide (DLE), which allows to operate on both gaseous and liquid fuel with ultra-low emissions of harmful substances.
In addition to the above, the SGT-400’s undeniable advantage is its high efficiency – 34,8 %. Such high value is achieved due to optimal fuel combustion in the combustion chamber and its outlet temperature of 1256 °С, as well as high compression ratio in the compressor of 16.7. At application of GTU as a mechanical drive the efficiency increases up to 36 %.
Design:
- 11-stage axial compressor, compression ratio πк=16,7
- DLE tubular-ring combustion chamber, outlet temperature 1256 °C
- 2-stage turbine with air cooling of both stages
Application:
- in simple cycle
- combined cycle
- in combined heat and power generation (CHP)
- on offshore platforms for power generation
The SGT-400 has proven itself in the oil and gas industry due to its outstanding reliability, maintainability and ability to operate on a variety of fuels.
