<p>COAL BURNING HEATING APPARATUS A coal burning heating apparatus has a grate assembly supported above an incoming primary air supply and beneath an adjustable and removable hopper assembly. The hopper assembly adjusts vertically for different coal sizes and enables top loading of the apparatus to be realized. A grate shaker assembly simultaneously pivots each of the horizontal grate elements, and a horizontal slot is provided in the grate assembly for insertion of a slicer member just above the horizontal grate structure to help remove ash. The grate and hopper assemblies are housed in a frame member having a long internal heat exchange path. The primary air, directed beneath the grate assembly, is constrained to follow a path through the grate assembly and the coal set thereon. The heating apparatus can also be employed for wood burning upon removal of the grate and hopper assemblies and their related components.</p> |
