Abstract
A solid fuel furnace having an oscillating grate plate solid fuel burner therein wherein the grate plates are in a stepped arrangement and every other plate moves together, in an opposite direction from the adjacent plates so that the solid fuel is kept moving down the step grate positively. Additionally, the solid fuel burner is mounted in a furnace housing which is designed to utilize the hot combustion gases to preheat incoming or makeup air for a blower used for supply air flow for heating. Baffles are used to provide a substantially elongated path for the combustion gases to ensure adequate heat exchange in a compact space.
Claims7
A furnace construction comprising a furnace cabinet having a solid fuel burner therein, wherein the burner comprises:
- a pair of burner side walls that are spaced apart in a longitudinal direction;
- a solid fuel inlet opening portion between said side walls, and adjacent an upper portion thereof;
- a plurality of three or more plate members arranged in a stepped arrangement, one above the other and each being partially offset in horizontal direction from the others in a descending arrangement from the solid fuel inlet;
- means fixed to the side walls to independently support each of said plurality of plate members for substantially horizontal movement between said side walls for limited reciprocal horizontal movement, the means to support supporting each plate members independently on the side walls;
- means independent of the means to support for driving said plate members along said means to support in generally horizontal movement;
- and
- drive link connected to each of said plate members and including means to cause opposite reciprocal movement of every other one of said plurality of plate members so that when an adjacent lower plate is moving in a first horizontal direction the next plate member above is moving in the opposite horizontal direction to thereby tend to move solid fuel materials downwardly over said stepped plate members.
