Intense Regime of Vibratory Combustion of Biofuel

Abstract

Experimental investigation of the vibratory combustion of a solid biofuel (wood pellets) has been conducted. In some experiments, a significant enhancement of acoustic radiation with vibratory combustion of the pellets was observed which was accompanied by the increase in their burnup rate. In the event of such a regime the flame temperature decreased, whereas the density of the heat flux on the combustion-chamber wall increased due to the turbulization of the boundary layer. An empirical-theoretical dependence to calculate heat transfer in intense regimes of vibratory combustion of the solid biofuel has been obtained.
