Environmentally Safe Charcoal-Based Heat Source

Abstract

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.

         2 . The heat source of  claim 1 , wherein the heat source is compromised of a pre-fabricated paper or paperboard material. 
     
     
         3 . The heat source of  claim 1 , wherein said charcoal-based fuel comprises a single-use amount of charcoal. 
     
     
         4 . The heat source of  claim 1 , wherein the heat source may be flat-packed following initial assembly, 
     
     
         5 . The heat source of  claim 1 , further comprising an inner chimney insert which provides structural support following final assembly, contains a set of safety matches, and permits removal of said inner chimney insert for use as a support base for said heat source. 
     
     
         6 . The heat source of  claim 5 , further comprising a striking surface associated with said inner chimney insert for providing surface for striking said safety matches. 
     
     
         7 . The heat source of  claim 1  wherein said charcoal fuel particles are treated with a flammable substance to enhance combustion. 
     
     
         8 . A method for forming an environmentally-safe, portable, disposable, and combustible charcoal-based heat source, comprising:
 forming a first combustible inner, vertical, upright chimney structure, and a second combustible, outer, vertical, upright wall structure surrounding said chimney structure;   forming an inner chimney flue defined by said chimney structure for receiving air for igniting and burning said charcoal-based heat source;   forming an outer flue defined by the outer wall of said first inner, vertical, upright chimney structure and the inner wall of said second, outer, vertical, upright wall structure, said outer chimney for exhausting combustion fumes from said charcoal-based heat source;   forming a bottom wall member secured to said inner chimney flue and said outer chimney flue and formed of a combustible material so as to be consumed during the ignition of said charcoal-based fuel;   forming a inner chimney insert placed inside of said inner chimney flue that stores said safety matches and may be removed to be used as a base for said heat source, is formed of a combustible material so as to be consumed during the ignition and burning of said charcoal-based fuel;   forming an ignition ring associating with the bottom of said inner chimney flue and the bottom of said outer chimney flue, said ignition ring for establishing a sustained ignition of sufficient duration to ignite uniformly the charcoal-based fuel; and   associating said inner chimney flue, said outer chimney flue, said inner chimney insert, and said ignition lattice to provide rapid and uniform burning of said charcoal-based fuel.   
     
     
         9 . The heat source forming method of  claim 8 , further comprising the step of forming said heat source to comprise a pre-fabricated paper or paperboard material that can be folded flat. 
     
     
         10 . The heat source forming method of  claim 8 , further comprising the step of forming said charcoal-based fuel from a single-use amount of a charcoal material. 
     
     
         11 . The heat source forming method of  claim 8 , further comprising the step of forming an inner chimney insert for structural support following final assembly, containing a set of safety matches, and permitting the removal of said inner chimney insert to be used a support structure for base of said heat source. 
     
     
         12 . The heat source of  claim 11 , further comprising the step of forming a striking surface associated with said inner chimney flue for striking said safety matches.
