Gasification offers one of the cleanest and most flexible ways of converting coal and low-grade fuels into high-value products – electricity, chemicals or synthetic fuels. Combining gasification with advanced gas turbines in Integrated Gasification Combined Cycle (IGCC) power plants results in a highly efficient technology for coal-based power generation. Gasification can offer environmentally friendly plants with lower emissions and the combination with readily available technology for CO₂ Capture and Storage (CCS).
The entrained-flow Siemens Fuel Gasifier (SFG) is able to convert a large range of fuels and is ideally suited for lower-rank fuels like lignite with high ash and moisture content. The technology with its unique cooling screen design and the efficient dry-feeding system is based on more than 30 years of continuous product development.
Main Features of Siemens Fuel Gasification Technology
- Dry solids feeding for high efficiency and low O₂ consumption
- Top-mounted dust burner with extended burner lifetime
- Cooling screen for high availability and low maintenance
- Full water quench for simple and reliable design

Gasification Test Center
The Siemens Gasification Test Center is located at our headquarters in Freiberg, and is one of the most comprehensive gasification test facilities in the world. More than 60 different fuels have been tested so far, which gives Siemens a rich body of experience.
The centerpiece of the Siemens Gasification Test Center is a 5 MWth gasification reactor which is complemented by a range of feedstock preparation systems and related gas cleaning process units. At the Siemens Gasification Test Center, a broad range of test conditions can be simulated. It is used to:
- Determine detailed analytical data of feedstock and gasification products.
- Optimize feedstock preparation to maximize efficiency and carbon conversion rate.
- Determine optimum gasification process conditions.
- Gain valuable information about expected products and environmental performance.
Dry Feeding Test Rig
The Siemens Gasification Test Center furthermore provides a test rig for high-pressure coal feeding. This test rig consists of a large-scale, fully equipped dry feeding system and can be used to find optimized feeding solutions. In particular, it allows the following aspects to be explored:
- Investigation of fluidization behavior under elevated pressure conditions
- Comparison of different coal density and velocity measurement systems
- Investigation of different feeding gases for solid feeding
- Test of alternative dry feeding systems
