Filed: 1979-10-13
Abstract: PURPOSE: To obtain an improved combustion air control in a flat-shaped petroleum combustor by making an air control board and a top plate arranged within a gap between an inner and an outer combustion cylinder of bar materials, thereby protecting the combustion air control from any thermal expansions of these board and plate.  
     CONSTITUTION: In the petroleum combustor wherein a flat inner combustion cylinder 3 is disposed on a fire tray 2 on the upper side of a laterally elongated wick casing 1 and a flat outer combustion cylinder 4 surrounds the inner cylinder 3, there are arranged the air control member 6 within the gap 5 defined between these inner and outer cylinder 3 and 4 and the top plate 7 at the upper part of the gap 5 for the covering purpose thereof. In this instance, the air control member 6 and the top plate 7 are made of bar materials. In arranging these member 6 and plate 7, they are not fixed at both ends. In such an arrangement, if these member 6 and plate 7 are subjected to the combustion heat, they expand mainly in the longitudinal direction and very slightly in the lateral direction because the diameter thereof is very small. Thus the combustion air control is substantially free from the influence of the thermal expansion of these member 6 and plate 7, thereby ensuring a stable control without fail.
