Abstract

784,765. Burners. OFU OFENBAUUNION GES. Sept. 27, 1955 [July 19, 1955], No. 27523/55. Class 75(1) [Also in Group XII] Fig. 1 shows a burner duct 8 so shaped that flames issuing in whirl formation from a burner 1 pass over the face of wall 4 as shown the back flow of atmosphere from a closed furnace chamber being repelled in the duct mouth. The burner of Fig. 2 comprises fixed housing 1 and nozzle mouthpiece 36 and a rotatable and axially movable sleeve member 34 with a nozzle part 35. The part 35 and piece 36 are toothed at their edges in their plane of division in the manner of a ratchet coupling the tooth, backs 39 each having a surface of helical form such that rotation of the sleeve, effected by movement of a lever 41, either forms gaps 55 of adjustable size between 35 and 36 or causes the teeth when in full engagement, to form a closed ring. Combustion air passes to the burner duct via a duct 3 and the openings 55 whilst fuel passes to the nozzle part 35 through a duct 2 and the sleeve 34. Rotation of sleeve 34 is limited by a fixed pin 42 interengaging an arc-shaped slot in a projection 44 fixed to the sleeve. In the burner of Fig. 4 liquid fuel is fed through pipes 15, 17 to an atomizing cup 18. Pipe 17 is disposed within a shaft 23 driven by a motor 16 and mounting a fan 21. Air to assist fuel atomization, is drawn in through damper-controlled duct 19 by the fan and discharged through annulus 22. Combustion air enters through duct 3 and is whirled by an adjustable device 25 before passing through an annulus 26 to the duct 8. A baffle wall 10 is arranged in the furnace chamber in front of the duct 8. Fig. 5 shows a centrally apertured annular disc-form baffle 60 placed within the duct mouth whilst Fig. 6 shows a form of duct in which cross-sectional views taken through the duct no longer represent concentric circles, as has been hitherto assumed, but form eccentric circles. The disc 60, Fig. 5, may be suspended such, that it may be moved relative to the duct mouth so as to increase or decrease, as required, the annular gap between disc and mouth. The burner fuel may be liquid, gaseous or pulverized coal.
