Eshleman, R D

This patent describes a particle fuel burning furnace having an upper particle fuel holding and combustion chamber, a lower combustible gas afterburning chamber and means forming at least one passageway interconnecting a bottom of the upper chamber and a top of the lower chamber. An improved particle fuel diversion structure consists of: (a) an elongated fuel diverter block having a recessed cavity formed therein; and (b) means disposing the inverter block in the upper chamber in spaced relationship above the bottom of the upper chamber and with its recessed cavity overlying the passageway, the diverter block coacting with the upper chamber bottom and the passageway-forming means to define a flow path from the upper chamber to the lower chamber which passes along the bottom of the upper chamber under the diverter block, upwardly into the cavity of the diverter block, and then downwardly through the passageway so as to cause an increase in the dwell time of flow entrained particles in the upper chamber and thereby promote combustion of the particles before they reach the lower chamber.
