The Shell Coal Gasification Process (SCGP) uses an upflow, entrained flow gasifier operating on a dry feed at slagging temperatures (Fig. ). The upflow arrangement allows separation of syngas and slag largely within the reactor itself. Typically there are four sidemounted burners located in the lower part of the reactor.
The Shell gasification technique including control has already been extensively used in pulverized coal gasification process (Zheng et al., 2005). Another approach control in Wei et al. (2014 ...
The mineral in coal is transformed to the fly ash of different particle sizes during the entrained flow coal gasification, causing the ash deposition problem on the radiant syngas cooler. In this study, the fusion behavior of fly ash collected from a Shell coal gasifier was analyzed by particle sieving.

Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...
