Lurgi Dry-ash Gasifier | netl.doe.gov - National Energy …
The Lurgi gasifier is a pressurized, dry-ash, moving bed gasifier that produces syngas from lump coal, steam, and oxygen as an oxidant. A high ratio of steam to oxygen helps moderate the temperature such that the ash does not melt, but rather is removed as dry ash.
Lurgi Process - an overview | ScienceDirect Topics
The Lurgi process is the gasification method most widely employed in industry. It is used to produce town and industrial gas in Australia, Czechoslovakia, the German Democratic Republic, the Federal Republic of Germany, South Africa, the United Kingdom and other countries.
Lurgi Dry Ash Gasifier - an overview | ScienceDirect Topics
The Lurgi dry-ash gasifier is a pressurized, dry-ash, moving-bed gasifier. Sized coal enters the top of the gasifier through a lock hopper and moves down through the bed. Steam and oxygen enter at the bottom and react with the coal as the gases move up the bed.
TheLurgi gasifier is a movingbed reactor in whichcoal moves downward under gravity countercurrent to the upward flowing gasification agent, a mixture of superheated steam and 98.5 percent pure oxygen. The coal bed is supported by.
