The Siemens SGT-800 A 50-MW-class industrial gas turbine

Siemens SGT800 Gas Turbine Overview

Introduction to Siemens and the SGT800

• Siemens emphasizes the importance of a reliable, cost-effective power supply that meets or exceeds environmental regulations for sustainable business practices.

• The SGT800 gas turbine is designed for various power industries, including independent power producers, utilities, municipalities, and oil and gas companies like refineries.

Development and Evolution of the SGT800

• Developed in Sweden during the 1990s, the SGT800 was initially introduced as a 43-megawatt industrial turbine but has evolved to exceed 50 megawatts based on application needs.

• The turbine's design benefits from continuous improvements derived from extensive operational experience with existing Siemens gas turbines.

Key Features of the SGT800

• The SGT800 combines robust design with high efficiency and low emissions, offering flexibility in fuel types, operating conditions, maintenance concepts, and ratings to meet diverse market demands.

• It features a single shaft engine with a simple two-bearing rotor design for enhanced reliability and ease of maintenance. The compressor includes 15 stages with variable guide vanes for optimal performance.

Advanced Combustion Technology

• A dual-fuel DLE (Dry Low Emission) system allows clean combustion without complex burner staging while maintaining excellent fuel flexibility for various gas compositions. This results in world-class emission performance with low NOx and CO levels.

• Maintenance-friendly designs allow easy removal of burners for servicing while ensuring high operational efficiency across varying load ranges.

Reliability and Maintenance Solutions

• Reliability was prioritized during development; reported fleet reliability averages over 99% over five years demonstrate this commitment to quality engineering.

• Two package options are available: the classic package integrates components on a single base frame while allowing external skid placement for mechanical systems; this facilitates easier transport and installation at sites.

Installation Efficiency

• The complete skid-mounted package option includes all necessary components (gas turbine, gearbox, generator) which reduces installation time to less than 60 days through its single lift capability—enhancing availability through quick core engine exchanges if needed.

Combined Heat and Power Applications

• Operating in combined heat and power cycles maximizes energy conversion efficiency; Siemens offers flexible plant configurations tailored to specific customer requirements using one or more SGT800 turbines as core units in powerful plants.
