摘要： A vaporizer and burner unit for an oil or kerosene space heater comprises three elongated, vertically stacked fuel mixture flow chambers A, B and C respectively defined between a lower U-shaped frame member 19b and the sloping bottom wall 26 of a flanged, upper U-shaped frame member 19a nested on the lower member, between the wall 26 and an inverted V-shaped pressure plate 27 having a plurality of fuel mixture feed holes 28 therein, and between the plate 27 and a burner plate 30 having a plurality of flame slits 31 therein. Fuel is fed into one end of the chamber A onto a heated vaporizer block 21, and combustion air blown in through a side window 24 adjacent the block and through a concentric gap 25 around the fuel supply line 12 mixes with the vaporized fuel and flows down chamber A and into chamber B through an end opening 29. The mixture then disperses through the holes 28 into chamber C and through the flame slits 31 to a spark igniter 62. Secondary combustion air is blown up through holes 32 in the upper frame member flanges and funneled into the flames by converging guide plates 33 mounted on the flanges. The zig-zag flow chamber arrangement implements thorough fuel-air mixture and preheating, and the holes 28 and 32 are staggered with respect to the slits 31 to promote uniform and complete combustion.
