Abstract

A pot burner has a circularly cylindrical combustion space 10 with openings 60, 62, 64 in its wall for the supply of combustion air and with an inlet in its floor 32 for the liquid fuel. Concentrically in the combustion space 10 there is placed a first cage 28 with a smaller diameter and a second cage 42 with a larger diameter than the circular outlet 18 for the combustion gases. The first cage is shut off at the top by an upper cover wall 26 whereas the second cage 42 is shut off at the top by an annular outer part of the cover wall at a lower level. The second cage 42 is divided into an upper annular chamber 36 and a lower annular chamber 38 by a perforated ring 46. The floor 14 forming the bottom of the combustion space 10 is covered over by a shield 82 to prevent the floor 14 from being cooled by incoming cold air for combustion.
