Boiler apparatus for combusting processed agriculture residues (PAR) and method

摘要

An apparatus that extracts energy from processed agriculture residue (PAR) such as dried distiller grains or rapeseed as a biomass fuel having about 12% by weight or less moisture combusted in a vertically elongated combustion chamber having at least one suspension burner that projects a flame down a longitudinal axis of combustion chamber for transferring heat to heat collection surface located radially from the flame, an exhaust opening vertically spaced from a distal end of the flame containment portion and vertically spaced lower of a substantial majority of the heat collection surface, and a temperature modulator that supplies a cooling air. A method of extracting energy from PAR fuel is disclosed.
