ABSTRACT:
A solid fuel furnace includes a vibratory bowl for its fuel bed. Structure in the furnace defines a fuel chamber over the central part of the bowl and a combustion chamber over the outward part of the bowl. Fuel is distributed outward by a central cone on the bowl. Primary air is fed beneath the rim of the cone into the fuel in the combustion chamber. The vibratory motion keeps the fuel particles evenly distributed and prevents blowholes from developing, leading to improved combustion. The vibratory motion also marches ash particles up a spiral groove in the circumferential wall of the bowl to facilitate ash removal from the fuel bed.
