Abstract

Three-dimensional computational fluid dynamics (CFD) modeling on gasification performance in an one-stage entrained bed coal gasifier (Korea SCGP gasifier) was performed for parametric studies with various O2/coal ratios (0.1, 0.3, 0.5, 0.7, 0.9, and 1.1) and steam/coal ratios (0.01, 0.05, 0.1, 0.15, and 0.2) using a commercial code, ANSYS FLUENT. The CFD modeling was conducted by solving steady-state Navier-Stokes equations with the Eulerian-Lagrangian method. Chemical reactions were solved via the Finite-Rate/Eddy-Dissipation Model for gas phase. Illinois #6 coal and design coal for the Korea SCGP gasifier were used for validation of our model and parametric study, respectively. In order to verify our CFD analysis results, actual operating data were compared with our results. Optimal conditions of O2/coal ratio and steam/coal ratio for the Korea SCGP gasifier using design coal were obtained as 0.7 and 0.05, respectively. Carbon conversion efficiencies, cold gas efficiencies, exit temperature and species mole fractions were also calculated by the modeling.
