Journal Article: South Australia to build High Temperature Winkler gasifierSouth Australia to build High Temperature Winkler gasifier
During coal gasification, coal is reacted with oxygen, steam and carbon dioxide to form a gas ... Fluidizedbed gasification, invented in 1922 by Winkler at BASF in Germany, has the advantage of a fairly simple reactor design. In this process, the air and steam flow required for gasification is sufficient to fluidize the bed of coal, char and ...
The Winkler process for the gasification of coal has been in successful commercial operation since the middle 1920s. In the fluid bed of the gasifier coal reacts with a mixture of air or oxygen and steam. The gas leaving the gasifier is only a mixture of H2, CO, CO2, N2, and CH4. The basic process is discussed along with the heat and material balances and the advantages of the Winkler system.
article{osti_, title = {Gasification of Pittsburgh No. 8 coal in Rheinbraun's atmospheric HighTemperature Winkler process development unit}, author = {Bellin, A and Adlhoch, W}, abstractNote = {Seven oxygenblown gasification tests with Pittsburgh No. 8 coal were carried out in the atmospheric HTW process development unit, with carbon conversions of up to 92 percent being reached.
This is also the case for the Lurgi pressure gasification process carried out in a mechanically agitated solid bed at ca. 1200°C (as used in burg in South Africa), for the KoppersTotzek process in which the coal is used in the form of flyash (atmospheric pressure, 1400 to 1600°C) and for the Winkler process operating with a ...
Coal gasification is a difficult process due to high gasification temperatures and low thermal efficiencies ... the Winkler process with 70+ reactors (Bogner and Wintrup, 1984), the HRL process (Anon, 2007), the KBR (Smith et al., 2002), and UGas technology (Vail, 2007).
This fluid bed gasification process was originally developed in the 1920s by Fritz Winkler of BASF in Germany for the gasification of lignite coal. In the 1970s, Rheinbraun (now RWE) improved the process by operating the atmospheric pressure gasifier at a higher pressure to increase the carbon conversion and to improve the quality of the syngas ...
(HTW) coal gasification process. The HTW process constitutes a further development of the Winkler fluidised bed gasification originally working at ambient pressure. The develop ment work was first focused on the production of chemical synthesis gases from lignite. In the mid 80s, the requirement of utilising the process in IGCC plants for ...
Applications range from the Winkler process, one of the first commercial applications of fluidizedbed technology, to the more recent HTW (hightemperature Winkler) combinedcycle powergeneration process. Coal gasification with O 2 and H 2 O in a fluidizedbed reactor involves pyrolysis, combustion and steam gasification. To understand the ...
The Winkler atmospheric fluidbed process was the first modern continuous gasification process using oxygen rather than air as blast. The process was patented in 1922 and the first plant built in 1925. Since then some 70 reactors have been built and brought into commercial service with a total capacity of about 20 million Nm3/d (Bogner and ...
The High Temperature Winkler (HTW™) process is a variant of the fluidized bed gasification processes. It originates from the Winkler process originally developed by Fritz Winkler in the 1920's. The intention was to develop a process to produce syngas with increased amounts of hydrogen and carbon monoxide.
bed gasifier was patented in 1921 by Winkler, and synfuels production from coal was common practice in Germany during world war II. According to the Gasification Technologies Council, in 2007, some 144 gasification plants and 427 ... Entrained reactor: KoppersTotzek, Shell Coal Gasification Process (SCGP), Prenflo, Siemens, GE Energy,EGas ...
The first application of the fluidizedbed gasifier in the gasification process is the original Winkler process. In the Winkler process, steam and air (or 02) are used at atmospheric pressure. The schematic of a typical Winkler gasifier is shown in Figure The coal (brown coal coke, subbituminous, or bituminous coals) is...
The HTW process is a further development of the Winkler coal gasification process which originally operated at ambient pressure and is the result of decades of systematic enhancement by the RWE Group in collaboration with Uhde as the engineering partner. Its main advantages are its improved feedstock utilisation, its much bigger gasifier ...
The HighTemperatureWinkler (HTW) process is based on a bubbling fluidized bed and was further developed by RWE and thyssenkrupp Industrial Solutions until the 1990 ...

The HighTemperature Winkler (HTW) technology is the most highly developed gasification technology utilizing biobased feedstocks. The process was originally developed in the 1920s by the German energy company Rheinbraun AG utilizing lignite coal. Over the years, the technology has been significantly improved to achieve better results and has ...
The paper presents the High Temperature Winkler (HTW) gasification process which is designed to utilize low rank feedstock such as coals with high ash content, lignite, biomass etc. The process is characterized by (i) a bubbling fluidized bed, where coal devolatilisation and partial oxidation of coal char and volatiles take place and by (ii) a ...

Fluidization technology has evolved significantly over the past 100 years, following the development by Winkler in 1922 [1] of the first prototype for this modern concept. Since then, fluidization has found widespread applications in process industries, with coal/biomass combustion or gasification (, Refs.
To provide basic information on why coal gasification is needed and what processes are available or under development, Fluor Corp. has compiled an overview of coalgasification technology that includes descriptions and diagrams of processes that are 1) commercial (KoppersTotzek, Lurgi pressure, WellmanGalusha, and Winkler), 2) ready for development (British Gas Corp./Lurgi slagging, Shell ...
