Abstract
A campstove burner includes a burner box which is located above the burner pan of the burner. The burner rings are positioned between the burner pan and the burner box, and a fuel and air mixture within the burner box flows through the burner rings where it is ignited. Since the burner box is located above the burner pan, liquid fuel within the burner box will flow through the burner rings and will be ignited in the burner pan outside of the burner box. The burner box includes an L-shaped aspirator tube for mixing fuel and air. An inlet end of the aspirator tube communicates with a source of primary combustion air, and a fuel tube extends into the outlet end of the aspirator tube for aspirating combustion air into the inlet end. The burner box includes a generally cylindrical sidewall and the outlet end of the aspirator tube directs the fuel and air mixture generally tangentially to the inside of the cylindrical sidewall to promote swirling and mixing of the fuel and air.
