Abstract: 14,781. Antal, G., and SzÛkely, L. July 11. Atmospheric vapour burners; vaporizing-apparatus. -Relates to burners of the kind in which liquid fuel is vaporized and then mixed with air in a trough-shaped chamber before being burned. The apparatus is adapted to be placed in an ordinary stove in place of the usual grate. In one construction, Fig. 1, oil from a reservoir flows through the inlet 10 down the supply-plate 11, into the vaporizer 2, and thence into the trough 13 in the mixing-chamber 3 by way of the opening 12. On the oil in the trough being ignited, vapour issues through the opening 12 and mixing with air entering at openings 15, regulated by means of a slide, partly burns beneath the vaporizer, combustion being completed in the perforated fire-box 4. Secondary air is supplied to the fire-box 4 from beneath the trough 13 and through the openings 16, entering the apparatus through supplyregulating openings 17. The discharge.opening 12 may be in the form of a slot, which may be subdivided into a number of openings preferably by the ribs on the cleaning-door 14. The plate 8, which supports the burner in the stove 1 in place of the usual grate, serves to cover the vaporizer; the plate 5 deflects the flame on to the stove walls. In burners for small stoves the vaporizer is of such a size that only part of the oil is vaporized in it, so that the preliminary heating flame is maintained in part by vaporized, and in part by unvaporized oil. The combustion box 4 may in some cases be dispensed with, the secondary air being supplied through an air passage arranged above the vaporizer. In the modification shown in Fig. 5, the vapour-discharge opening 12 is arranged in the end.wall of the vaporizer. The air for combustion passes through an air regulator 25. In the arrangement shown in Fig. 7, the vapour issues from the vaporizer through an opening 20 formed between the corrugated wall 22 and the door 14, which is hinged or otherwise displaceable and may be actuated by means of a regulating-screw to adjust the opening. A portion of the air for combustion is conducted into the mixing-chamber through openings in a crosspassage 23. The vapour issuing from the vaporizer may induce a supply of air through a pipe 28 when the apparatus shown in Fig. 11 is used, the secondary supply entering through the opening 31 in the door 30. Fig. 18 shows a construction suitable for large burners, in which the vaporizer is inclined, and the oilsupply plate 11 is pivoted, so that it may be set by a lever to deliver the oil supplied at 10 either into the retort or direct through the opening 12, over the stepped grate 53, into the trough for preliminarily heating the vaporizer. The air is supplied through the openings in the grate 53, by way of the passage 46 and chamber 60, where it is heated, and through passages 6. A further supply of heated air for secondary combustion passes to the burner through the device shown in Fig. 20, which is arranged above the burner, and is in contact with the interior of the stove walls. It comprises a perforated air chamber, to which air is admitted through a hinged regulating-door 57. Further means for regulating the air supplies comprise a slide 45 and a door 44, which are connected by rods 49, 50. When, by means of the handle 48, the door 44 is pushed in and the supply of air for primary combustion is decreased, the slide 45 uncovers part of the openings 16 and increases the secondary 'air supply. The reverse motion increases the primary supply of air and decreases the secondary supply. The door 44 is hinged to one of the side rods 50 so as to be capable of rotation in a vertical plane to facilitate withdrawal of the trough and the vaporizer. In a modification of the arrangement shown in Fig. 18, the vaporizer is horizontal and the stepped grate is dispensed with, the door 44 closing on to the vaporizer front. The supply of air over the vaporizer top, in this case, is delivered in the opposite direction to that of the mixed gases flowing to the combustion chamber, and preferably the oil-supply plate is integral with the end wall of the vaporizer, 'and the floor of the latter formed with a channel in the middle. The apparatus may be of cast-iron.
