Numerical Analyses and Engineering Calculations for the Conceptual Design of Compact Gasifier

摘要

Coal gasification technology is considered as the best alternative forrnboth of the high efficiency and clean coal utilization. However, it is stillrnfairly expensive, so many coal gasification technologies are underrnbeing developed to achieve lower capital cost. We aim to develop suchrntechnology by adopting special feature of swirl burner. At first, heat &rnmass balance simulation by process simulator was conducted tornestimate gas composition. Next, CFD analysis for reactive flow in therntop feeding multi-burner gasifier was performed. In addition, somernengineering calculations were carried out for the conceptual design of 3rnton/day-class coal gasification system.
