GASIFICATION

The Winkler process, developed in the 1920s is still in commercial use at some locations. Entrained flow reactors operate at high temperatures (1500°C) and high pressures with short residence times; the powderedcoal is entrained and gasified in cocurrent flow by the gasifying medium. Ash in the coal forms a liquid slag.
