Title: Improvements relating to air control devices of oil burners
Inventor: FORWARD HERBERT
IPC: F23D11/24
Filed: 1957-09-10
Abstract: 843,642. Burners ; air supplies. GRIFFIN, SMITH & PARTNERS Ltd. Dec. 9, 1958 [Sept. 10, 1957], No. 28577/57. Class 75(1). - Air control means in an oil burner are operated by a pressure sensitive member controlling the delivery of oil to the burner and arranged to give an increased supply of combustion air during starting, the air supply being restrainedly decreased throughout the starting period so as finally to achieve the value appropriate to normal running. Air from a fan or blower is supplied to the burner, the flow being restricted by a pair of relatively rotatable slotted discs, part of one of which is shown at 9, the effective area of the opening provided by the discs being governed by the position of the post 16 which is attached to both the rotatable disc 9 and the piston rod 15. The burner 6 illustrated in Fig. 1 (not shown), is of the type described in Specification 843,641 and has a fuel supply valve operated by bellows subjected externally to the pressure in the fuel oil supply. The interior of the bellows are connected by the pipe 13 to the cylinder 11 in which is sealed by rings 28 a piston 12 attached to the rod 15. A portion 12a of the piston is of reduced diameter and connects the sealed portion to the hollow portion 12b round which is a fine clearance 17 with the cylinder, the open end of the hollow portion being closable by a ball 19. The cylinder 11 is also connected to the cylinder 23. Both these cylinders, the pipe 13 and the interior of the fuel valve bellows are oil-filled. On operation of the fuel supply valve, the contraction of the bellows injects a slug of oil into the cylinder 11 via the bore 18 and ports 20 in the portion 126 which then becomes sealed by the ball. The excess pressure on the bellows side of the piston moves the latter against the resistance of the spring 26 to increase the air supply. Slow leakage of oil through the clearance 17 allows the pressure on opposite sides of the portion 12b to be equalised by outward movement of the piston 24 while the spring returns the disc 9 to the setting for normal burner operation. The thread- and-nut 29 allow adjustment of this setting. The cylinders 12 and 24 may be in separate blocks connected by a pipe. The bellows may be replaced by a flexible diaphragm.

Abstract: 463,573. Controlling gas burners. EVERED & CO., Ltd., and DAVIES, G. Oct. 17, 1935, No. 28660. [Class 135] [Also in Group XI] A valve device for controlling the gas supply to burners adapted for electrocatalytic ignition, has the main and byepass valves and the switch controlling the ignition actuated by a member subject to pneumatic impulses derived from a remote manually operated transmitter. The transmitter comprises a piston 19 adapted to be depressed against the action of a spring 20 by a hand lever 21 shaped so as to be stable in either of its extreme positions, which action may be assisted by a spring plate 23. The space below the piston 19 communicates through a pipe 17 with the space above a leaky plunger 15 provided with a permanent magnet core 15<a> and carrying at its lower end the main gas valve 16. The byepass valve comprises a sliding rod 11 having a groove adapted to co-operate with ports in a liner 12 supported by an insulating sleeve 10, said ports communicating on the one hand through passage 5d and pipe 6 with the main inlet 4<a> and on the other with the pipe 14 leading to the byepass burner. When the lever 21 is manipulated to reduce the pressure in the conduit 17, the plunger 15 is lifted to open the main valve and at the same time the plunger engages and lifts the rod 11 to establish a supply to the pilot burner and by the engagement of a head on the rod 11 with a contact 9a itself in contact with a central contact in a battery establishes an electric circuit through the byepass pipe 14 and igniting device. As gas seeps past the plunger 15 it falls until the head on the rod 11 engages the upper end of the liner 12 whereafter the plunger is magnetically suspended from the rod to hold the valve open. To close the valve the lever 21 is manipulated to compress the fluid in the conduit 17 ; such pressure acting on the plunger overcomes the magnetic attraction and allows the valve to close.
