PURPOSE:To contrive to keep uniform complete combustion by preventing the thermal deformation from occurring during the combustion of a burner by forming a structure wherein a cantilever holder is equipped in a flat combustion chamber and at the same time cantilever partition plates with openings are provided in the front and rear spaces formed between the flats of said combustion chamber and an outer tube. CONSTITUTION:Because a front and a back partition plates 21 and 22 do not press a portion of the wall surface of a combustion chamber so as to cause wavy deformation of the wall surface and keep the uniform planes and consequently prevent the wall surface from bending, a bad influence over the burning state and distribution of red heat is evaded and uniform complete combustion can be ensured over the whole region of the combustion chamber 17. Further, as for the danger of the generation of deforming stress towards the inside of the combustion chamber 17 by pressing with the front and back partition plates 21 and 22, a holder 20 provided in the combustion chamber 17 acts so as to keep the proper gap. At the same time, because the plates 21 and 22 and the holder 20 lie nearly at the same position (at the same height) in a horizontal cross section in parallel, their respective pressing forces balance with one another and consequently the normal shape of the combustion chamber can be kept.
