Gasification entrained flow gasifiers

Hitachi. This coal gasification technology is based on an oxygen-blown entrained flow gasifier, where the majority of experience has been gained in a 150 ton coal/day unit. The gasifier is a water-cooled tube that is lined by a high-temperature-resistant castable. Pulverized coal is pneumatically... 

All of these reactions are highly exothermic, providing heat for the subsequent endothermic gasification reactions. Because gasifiers operate under fuel-rich conditions, the 02 is completely consumed before these particular reactions have consumed all of the carbon. Reaction R-4.3 achieves thermodynamic equilibrium quickly enough at the high temperature conditions in entrained flow gasifiers so that chemical equilibrium can be assumed. 

At the heart of the GE coal gasification process is a top-fired slurry-fed slagging entrained-flow gasifier. Schematics of the typical Texaco gasification system are shown in Figures 4.10 and 4.11. 

The Great Plains Gasification Project—located in Beulah, ND, and now owned by Basin Electric, headquartered in Bismarck, ND—employs 14 Lurgi coal gasifiers in a 2.2 billion (1984 prices) project that has been in operation for nearly twenty years (Fig. 6-2). More advanced entrained-flow gasifiers dominate today s market, so this facility is not state of the art.
