SIEMENS SGT-2000E series gas turbine

Adaptation design: No gas film cooling structure, avoiding cooling channel blockage caused by ash accumulating fuels (such as heavy oil and crude oil), and expanding the fuel adaptation range.

(3) Combustion chamber

Structural form: Double silo type large volume combustion chamber with ceramic insulation cover, reducing the impact of direct flame radiation on turbine blades and extending component life.

Burner configuration: 8 burners per combustion chamber for SGT5-2000E, 6 burners per combustion chamber for SGT6-2000E; Adopting a hybrid burner and dry low NOx technology, the premixed combustion design reduces emissions.

Maintenance advantage: There is a manhole on the side of the combustion chamber, which can directly inspect the hot channel components from the burner to the turbine blades without disassembling the overall structure, improving maintenance convenience.

3. Three core advantageous characteristics

(1) Fuel flexibility: adaptable to multiple types of fuels, reducing fuel dependence

Gaseous fuels: standard natural gas, low calorific value natural gas, synthesis gas (IGCC output), naphtha derived gas, etc.

Liquid fuels: standard fuel, heavy oil, crude oil, kerosene, naphtha, and ash based fuels.

Adaptation technology: Provide specialized modified burners for unconventional fuels such as synthesis gas and heavy oil to ensure combustion stability and efficiency; Siemens has accumulated rich experience in unconventional fuel applications and can provide customized solutions for projects.

(2) Operational flexibility: adaptable to complex working conditions, fast response

Quick start stop: With standard static excitation and variable frequency starting system, it can accelerate from start-up to full load within 4 minutes, meeting the needs of power grid peak shaving, emergency power supply, etc.

Load regulation: Supports flexible adjustment of 50% -100% load, and can maintain low emission levels even under partial load, adapting to power grid load fluctuations.

Grid adaptation: With flexible grid support capabilities, it can adapt to different regional grid frequency requirements (50Hz/60Hz) and has strong stability.

(3) Maintenance convenience: reduce operation and maintenance costs, extend service life

Component replacement: All stationary and moving blades of the compressor and turbine can be replaced separately without disassembling the rotor and lower cylinder body, reducing maintenance downtime.

Inspection channel: A manhole is installed inside the combustion chamber, and the hot channel components (burner, turbine blades) can be directly inspected without disassembling the equipment.

Special adaptation: Design a structure that is easy to manually clean and inspect for the operation scenario of greyed fuel, reducing the impact of greying on equipment performance.

Lifespan design: The core components are made of high wear-resistant and high-temperature resistant materials, combined with optimized cooling and coating technology, to extend the service life of the components and reduce replacement frequency.

(4) Environmental performance: Low emission design, in compliance with environmental standards

Emission control: Using dry low NOx combustion technology and premixed burners, NOx emissions can be maintained at a low ppm level under ISO conditions, and even partial load operation can meet strict environmental requirements.

Energy saving design: High cycle efficiency reduces CO ₂ emissions per unit of power generation, while optimized combustion chamber and turbine design reduces fuel waste and improves energy utilization efficiency.
