Kunkel, Jr, R C

A furnace in which coal and cellulose fuel can both be burned on the same traveling grate. First means are provided for introducing coal onto the grate at one end, such that it traverses the full grate run before it falls as ash from the other end of the grate. Second means are provided for introducing cellulose fuel onto the grate at a central or middle location. Adjustable means are provided for varying the point at which the cellulose fuel is introduced onto the grate. If cellulose fuel having a relatively slow burning rate is being combusted, the adjustable means are set so as to introduce the fuel at a point on the grate further away from the discharge end. If cellulose fuel having a relatively fast burning rate is being combusted, the adjustable means are set so as to introduce the fuel at a point on the grate closer to the discharge end.
