A dynamic model of the Shell gasifier in an integrated coal gasification combined cycle (IGCC) is established based on physical principles, focusing on the timedependent accumulation and flow on the walls. Numerical simulations are carried out to explore the system dynamic performance with respect to step changes in the inlet oxygentocoal ratio and steamtocoal.

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 ...
