<p>An environmentally-safe, disposable, and combustible charcoal-based portable heat source includes a first combustible, inner, vertical, upright chimney structure, and a second combustible, outer, vertical, upright wall structure surround said chimney structure and an inner chimney flue defined by said chimney structure for receiving air for igniting and burning said charcoal-based heat source. An outer chimney flue defined by the outer wall of said first combustible, inner, vertical, upright chimney structure and the inner wall of said second combustible, outer, vertical, upright, wall structure, said outer chimney for exhausting fumes from said heat source. A removable inner chimney insert provides structural support for the heat source. An ignition ring establishes a sustained ignition to uniformly ignite the charcoal-based fuel.</p> |
