Abstract
Wood waste fuel is piled on a perforated grate within a combustion chamber. The fuel is burned by underfire air passing through the grate up through the pile. Ash forms at the bottom of the pile and is removed about a complete 360 degree perimeter where it falls into an ash pit and is subsequently removed from the burner. Fuel is fed to the burner through an elongated continuously expanding tube by a reciprocating ram feeder.
