Computational Fluid Dynamics Modeling of the Cold Condition Characteristic in an Entrained Flow Gasifier

Abstract

Entrained flow gasification technology has been attracted by gasifier researchers and companies for its wide-ranging feedstock adaptability and commercial scale availability. The optimization of the entrained flow gasifier is the critical thing for the development of entrained flow gasification technology. This paper presented a three-dimensional computational fluid dynamic (CFD) simulation for a better understanding of the cold condition flow characteristic in an entrained flow gasifier. The spraying angle, diameter and injection velocity of nozzles were found to observably affect the velocity distribution and mixing condition in the entrained flow gasifier. The numerical results could provide useful information for further research on the particle track and gasification reaction and an effective process for optimizing the gasifier and nozzle.
