1. A device comprising: (a) an inner chamber formed by an inner tubular wall, a top plate, and a dividing plate, said top plate having a mouth communicating with the external environment, said inner chamber adapted to receive fuel through said mouth; (b) an outer chamber formed by an outer tubular wall coaxial with said inner tubular wall, said top plate, and a base plate, said base plate having at least one aperture communicating with the external environment and being spaced from said dividing plate, said outer chamber comprised of a lower cylindrical portion under said inner chamber and an upper annular portion between said inner tubular wall and said outer tubular wall; (c) a plurality of circumferentially staggered lower passages through which said inner chamber communicates with said annular portion at said dividing plate; and (d) a plurality of circumferentially staggered upper passages through which said annular portion communicates with said inner chamber at said top plate; (e) whereby gases evolved in said inner chamber flow through said lower passages, rise through said annular portion, and flow through said upper passages into said inner chamber where they produce localized combustion primarily in said mouth, forming a flamecap.
