INTENSE REGIME OF VIBRATORY COMBUSTION OF BIOFUEL

Experimental investigation of the vibratory combustion of a solid biofuel (wood pellets) has been conducted. In some experiments, a signifi cant 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 fl ame temperature decreased, whereas the density of the heat fl ux 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.
