Abstract
In this paper, we first develop a new numerical scheme for a computational fluid dynamics code and then investigate the impact of the airflow configuration on the performance of a 300 MW tangentially fired furnace by both simulations and experiments. Four different secondary and two tertiary air arrangements are tested. It is shown that the newly developed 27-point discrete scheme enhances the performance of the code, offering a satisfactory prediction of the velocity field for the isothermal furnace flow. Further effort is made to examine the effects of airflow configuration on combustion performance, outlet temperature deviation, and heat loss due to combustibles in the bottom ash. Both simulations and operation trials suggest that, for the furnace investigated, when firing bituminous coal, the double V-shaped secondary air configuration has the best performance.
