Abstract
An improved burnpot assembly for a stove which allows clinker to be removed from the burnpot while simultaneously maintaining combustion includes a burnpot holder having an immovable floor, a burnpot movably supported on the burnpot holder, the burnpot including a front wall and an opposite back wall. The burnpot is movable with respect to the floor between a normal fuel burning position in which the walls of the burnpot and the immovable floor define a burnpot for combustion and a clinker removal position in which the burnpot is disposed laterally adjacent the immovable floor to allow clinker to drop from between the walls of the burnpot, such as into a clinker collection pan near the bottom of the stove.
Claims14
A burnpot assembly for a stove, comprising:
- a burnpot holder having an immovable floor;
- a burnpot movably supported on the burnpot holder, the burnpot including a front wall and an opposite back wall, the front wall and back wall connected together by members that allow the opposite front wall and back wall to be moved together as a unit with respect to the burnpot holder between a normal fuel burning position in which burning fuel may be deposited on the immovable floor between the opposite sidewalls, and a clinker removal position in which the burnpot is disposed laterally adjacent the immovable floor.
A process for removing clinker from a burnpot of a stove, comprising:
- adding fuel to a burnpot defined by burnpot walls and a floor, the walls being connected together and being movable with respect to the floor;
- burning fuel and forming clinker in the burnpot;
- moving the walls of the burnpot with respect to the floor and thereby causing the clinker to be removed from the floor;
- dropping the clinker from between the walls of the burnpot;
- moving the walls of the burnpot back into a position in which the burnpot walls and the floor together define a burnpot.
