HTW – High Temperature Winkler Gasification

The HTW fluidized-bed gasification process was developed in the 1920s in Germany by Fritz Winkler. Commercial-scale Winkler gasifiers were operated in over 40 applications around the world. In the 1970s, ThyssenKrupp Industrial Solutions together with Rheinische Braunkohlenwerke AG commenced with the development of a pressurised version of the Winkler gasifier – the High-Temperature Winkler (HTW) gasification process. The HTW process enables shorter residence time, higher reaction velocity, higher reactor throughput for larger plant capacity, higher carbon conversion rate, higher plant efficiency and improved syngas quality.
