Development of Euler-Lagrangian Simulation of a Circulating Fluidized Bed Reactor for Coal Gasification

A Computational Particle Fluid Dynamics (CPFD) model based on the Multiphase Particle in Cell (MP-PIC) approach is used for Shubarkol coal gasification simulation in an atmospheric circulating fluidized bed reactor. The simulation is developed on a basis of experimental data available from a biomass gasification process. The cross-section diameter of the reactor riser is 200 mm and the height is 6500 mm. The Euler-Lagrangian simulation is validated using experimental data available in the literature and also compared with an Euler-Euler simulation. The gasification reactions kinetics model is improved, and homogenous and heterogeneous chemistry are described by reduced-chemistry, with the reaction rates solved numerically using volume-averaged chemistry. The simulations reveal gas composition, temperature, and pressure interdependencies along the height of the reactor. The product gas composition compares well with the experiment and the temperature profile demonstrate good consistency with the experiment. The developed model is used for a case study of Shubarkol coal gasification in the circulating fluidized bed reactor

Coal gasification in circulating fluidized bed reactor

This research project is aimed at developing circulating fluidized bed gasification technology for coal being mined in Kazakhstan. The main goal is to construct a gasification technology for extra-high ash containing coals mined in Kazakhstan, particularly Ekibastuz, Maikuben, Mamyt and Torgay coals. To achieve this goal, the project will be developed in two main steps. The first step is modeling gasification process and designing the model simulation software. The second step is constructing circulating fluidized bed gasification technology
