摘要

The influence of the perforated plate characteristics that precedes the flame support layer in a newly designed bilayered porous combustor was numerically assessed. It is shown that a perforated plate with 1 mm diameter holes is able to provide the necessary quenching of the reaction front, leading to the stabilization of the flame within the pores of the flame support layer for all the range of operating conditions and is, thus, an appropriate choice. The influence of the diameter of the holes on the gas and solid temperatures, and on the emissions of pollutants, namely NO and CO, is discussed.
