Diameter of alumina balls effect on stabilization operation region for a reciprocal flow burner

Abstract

A reciprocal gas flow porous burner is computationally simulated for obtaining its stable operation region as function of equivalence ratio, filtration velocity and particle diameter, for two energy losses configurations schemes. Equivalence ratio and filtration velocity were considered over the range [0.1, 1.0] and [0.25, 1.0] (m/s). Lateral heat losses were studied at two scenarios: reactor coupled with and without heat exchangers. Results demonstrated increased stabilization in temperature profile, thus increased stabilization region for the reactor coupled with heat exchangers. Increase of particle diameter results in increased stabilization region for both energy losses schemes.
