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.
The Winkler gasifier is a fluidizedbed gasification system that operates at atmospheric pressure.

Objective is a commercialscale coal gasification facility producing clean mediumBtu gas (300 billion Btu/day) from 20,000 tons/day of bituminous coal. The process was narrowed down to either the Texaco process, the KoppersTotzek process, or a combination of those two. This document is a summary description of the plants for both processes.

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.
In the Shell gasification process, coal is crushed and dried and then fed into the Shell gasifier as a dry feed. The gasifier, as shown in Figure 8, is an oxygenblown, waterwall gasifier eliminating refractory durability issues. It is good for wide variety of feed stocks, from pet coke to lowrank coals and has been run on biomass as well.

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.
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 Sasolburg 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 ...
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.
