Abstract

In this paper, High-Temperature Air Combustion (HiTAC) method utilizing coal as fuel is studied numerically using Computational Fluid Dynamics (CFD). A case study was performed using the CFD code FLUENT 6.2 to investigate the effects of utilizing high temperature air combustion on a real 700MW coal-powered boiler operating on a tangential firing mechanism. The results obtained were consistent with the ones reported in the literature. For high temperature air, a bigger flame structure and higher average temperature inside the boiler was found. The firing performance is found to be improved mainly due to formation of stable flame which further leads to the reduction in ignition delay.
