Computational Fluid Dynamics Modeling of Coal Gasifiers

The water-gas shift reaction should be the only reversible reaction. The backward reaction given in Table 5.7 can be either calculated during the simulation with the help of the equilibrium constant or can be integrated as backward reaction, which is calculated a priori with the aid of equilibrium data, for example, from Aspen Plus [49].

Because the flow pattern inside gasification reactors is of prime importance to understand gasifier behavior, this section is dedicated to give an engineering-oriented and pragmatic overview how to approach the complex field of CFD utilization for coal gasification. On the example of internal circulating fluidized bed (INCI) concept development, explained in detail in Chapter 9, test calculations should be accomplished to understand the basic relationships of the system.
