Self-priming alcohol stove

An alcohol stove comprising:

• a burner cup having a base and side walls for storage of liquid alcohol;
• a top plate having upper and lower surfaces, said burner cup being attached to the lower surface;
• a main burner assembly attached to said burner cup at a location where said main burner assembly will consume alcohol evaporating from within said burner cup when said main burner assembly is ignited, said main burner assembly being on the upper surface of said top plate and comprising a perimetrical surface, defined by an inner edge and an outer edge, and openings between the inner and outer edges from which alcohol vapor escapes;
• a start-up burner assembly positioned adjacent said main burner assembly for ignition of said main burner assembly by flames from said start-up burner assembly;
• heat transfer means to transfer heat from said main burner assembly and said start-up burner assembly to a quantity of alcohol held by said heat transfer means within said burner cup distal from the side walls and the base, whereby the quantity of alcohol is vaporized, said heat transfer means comprising:
• (i) an inner wall extending downwardly into said burner cup from said top plate in alignment with the inner edge, wherein the inner wall defines an inner chimney where said start-up burner assembly is located;
• (ii) an outer wall extending downwardly into said burner cup from said top plate in alignment with the outer edge, wherein the outer wall and the inner wall define an outer chimney;
• and
• (iii) at least one screen located in said outer chimney said at least one screen extends outwardly from the inner wall;
• and
• a fibrous wick positioned in said outer chimney, wherein the quantity of alcohol held by said heat transfer means is absorbed by said fibrous wick.

An alcohol stove comprising:

• a burner cup having a base and side walls for storage of liquid alcohol;
• a top plate having upper and lower surfaces, said burner cup being attached to the lower surface;
• a main burner assembly attached to said burner cup at a location where said main burner assembly will consume alcohol evaporating from within said burner cup when said main burner assembly is ignited, said main burner assembly being on the upper surface of said top plate and comprising a perimetrical surface, defined by an inner and an outer edge, and openings between the inner and outer edges from which alcohol vapor escapes;
• heat transfer means to transfer heat from said main burner assembly to a quantity of alcohol held by said heat transfer means within said burner cup distal from the side walls and the base, whereby the quantity of alcohol is vaporized, said heat transfer means comprising:
• (i) an inner wall extending downwardly into said burner cup from said top plate in alignment with the inner edge;
• (ii) an outer wall extending downwardly into said burner cup from said top plate in alignment with the outer edge, wherein the outer wall and the inner wall define a chimney;
• and
• (iii) at least one metallic screen extending radially outwardly toward the outer wall and located within the chimney;
• and
• a fibrous wick positioned in said chimney, wherein the quantity of alcohol held by said heat transfer means is absorbed by said fibrous wick.

An alcohol stove comprising:

• a metallic burner cup having a base and side walls for storage of liquid alcohol;
• a main burner assembly attached to said burner cup at a location where said main burner assembly will consume alcohol in said burner cup when said main burner assembly is ignited, wherein said main burner assembly comprises an annular ring having an inner circular edge, an outer circular edge, and openings from which alcohol vapor escapes;
• a top plate having upper and lower surfaces, wherein said main burner assembly is on the upper surface of said top plate and said burner cup is attached to the lower surface of said top plate;
• an outer wall extending downwardly from the lower surface of said top plate in alignment with the outer circular edge, wherein said outer wall extends to a location above the base of said burner cup;
• an inner wall extending downwardly from the lower surface of said top plate in alignment with the inner circular edge, wherein said inner wall extends to a location closer to the base of said burner cup than said outer wall and wherein said inner wall and said outer wall are concentric cylinders;
• a fibrous wick between said inner and outer walls;
• at least one metallic screen contacting said inner wall;
• a fibrous wick within said inner wall;
• a wick cup for carrying said fibrous wick within said inner wall, said wick cup being provided with a small hole to restrict the contact of alcohol with the fibrous wick within said inner wall;
• a foam ring within said burner cup and surrounding the outer wall, said foam ring being positioned and having dimensions to prevent overfilling of and excessive pressure build up within said burner cup;
• a metallic disc positioned near the base of said burner cup and in contact with the base or side walls of said burner cup;
• and
• a burner cup wick in said burner cup on top of said disc and in contact with said inner and outer walls.
