摘要：

This article deals with the numerical modeling, development, and performance testing of a novel partial premix-type burner with a discrete porous medium using liquefied petroleum gas as fuel. The porous structure is made up of solid Al(2)O(3) spheres. The simulation is carried out with sphere sizes of 20 and 30 mm and with different layers of porous medium. The main objective of the study is to analyze the temperature distribution and emission characteristics of the porous medium burner compared with the conventional free flame combustion. Three-dimensional steady state combustion simulation is performed by FLUENT 6.2.16 and GAMBIT 2.2.30. The eddy dissipation model is employed for combustion, and the flow turbulence is simulated using the standard k-epsilon model with standard wall function. The results show that the burner has good combustion efficiency and significantly lower NO(x) and CO emissions compared to the conventional combustor. A test rig is fabricated and experiments are performed to validate the simulation results and are found to be in good agreement.
