ABSTRACT:
A combustion method in which heat is generated from particulate laden combustible gas containing mineral matter created from gasifying waste wood, coke or other combustible material in which the waste is fed into a pile, under-fire combustion air dries and gasifies the waste, oxidizing the fixed carbon in a first chamber to generate heat at a temperature less than the melting temperature of the non-combustible material so as not to form slag, adding air in the first chamber in an amount less than stoichiometric with the air introduced in a swirling fashion to move the particulate laterally away from the discharge of the primary chamber, impeding the movement of this particulate also by adding secondary combustion air in a downward swirling direction in the secondary chamber so that very little non-combustible material reaches the second chamber where melting can occur.
