gasifier. (Show more) coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a byproduct.

The High Temperature Winkler gasifier uses one of the oldest gasification technologies. The process was developed in 1926 by Rheinbraun AG in Germany using lignite coal. Approximately 16 plants with a total of 40 gasifiers have been built worldwide since it was introduced in 1926. In the 1970s, Rheinbraun (now RWE) improved the process by operating the gasifier at a higher temperature to ...

The process is based on the Winkler gasifier which was developed by Fritz Winkler in the 1920 s. It should be noted that this was the first commercial fluidized bed process. The differences of the HTW process to the Winkler process are a higher pressure, higher temperature and a post gasification zone (PGZ).

HTW™ process. 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.

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.
