Flame stabilization in a porous burner at the interface of two sections of alumina spheres

摘要

Development of porous burners has been encouraged by lower emissions standards as well as highly efficient characteristics. In this work, a method of flame stabilization in a porous media burner with a double section of alumina spheres is reported. The stable operating limits are predicted for a range of gas velocity and equivalence ratio. These limits allow the creation of the porous media permanent combustor by two different zone distinguished by the diameter of the alumina spheres. Temperature profiles and chemical products compositions were measured whose results confirm the hypothesis of the front combustion stabilization in the interface between two sections of alumina spheres.
