Description

LIQUID FUEL BURNER AND COMBUSTION APPARATUS Filed April 17, 1950 Patented June 2, 1953 LIQUID FUEL BURNER AND COMBUSTION APPARATUS John Stanley Clarke, Blacko, near Nelson, England, assignor to Joseph Lucas Limited, Birmingham, England Application April 17, 1950, Serial No. 156,461 In Great Britain May 23, 1949 2 Claims.
This invention has for its object to provide an improved liquid fuel burner adapted for use more particularly in the combustion chambers of jetengines, gas turbines or the like.
The accompanying drawing is a sectional side elevation illustrating one embodiment of the invention for use in a cylindrical combustion chamber surrounded by an air jacket.
Referring to the drawing, the nozzle is constructed from a pair of circular metal plates a, b of any convenient and suitable diameter. The plate a is formed at one side with a hollow axial shank adapted to be secured to a perforated supporting plate (I at the entrance of the combustion chamber. At the other side it is formed with a hollow central boss 6 adapted to carry the second plate I). The adjacent faces of the plates are shaped to form a shallow chamber f to which vaporised fuel can be supplied from a tube 9 having one end secured to the said boss. The plate a is of rather larger diameter than the plate '2), and the peripheral part of the latter is adapted to form with the adjacent face of the former plate a narrow annular orifice it through which the vapour can flow radially from the said chamber.
The vapourising tube is preferably of helical form, though it may be of any other convenient shape and is adapted to extend into the combustion chamber 2', the supply-end of the tube being preferably arranged to extend rearwardly to and through an air duct 9' at the rear end of the combustion chamber. The combustion chamber 1' and air duct 9' are surrounded by an air jacket 70 terminating in an air supply pipe m from which both the jacket k and the duct 7' are fed with air from a blower or other source.
The plate d above mentioned which carries the nozzle has secured to it a bell-shaped shield 0 which at its larger end surrounds the nozzle, and which lies within the duct 9' which is of truncatedconical form. This part 9' serves to direct air into the air jacket, and the air entering the part a is divided by the part 0 into two concentric streams. The inner stream flows through the part c and plate at to the region around the nozzle, and the outer stream flows to the peripheral region of the combustion region where it meets with air which enters the said region from the jacket through perforations as 10.
By this invention an efficient burner can be provided in a very simple and robust form.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. A liquid fuel burner comprising in combination a nozzle formed by a pair of coaxially arranged metal plates and having an annular discharge orifice between the peripheral portions of said plates, a supporting shank on and extending axially from one side of one of said plates, a hollow boss on and extending axially from the other side of the last mentioned plate through the other plate which is carried by said boss, and a vaporising tube secured at one end to said hollow boss.
2. Liquid fuel combustion apparatus comprising in combination a combustion chamber, a burner nozzle arranged at one end of said chamber, said nozzle being formed by a pair of coaxially arranged metal plates and having an annular discharge orifice between the peripheral portions of said plates, a supporting shank on and extending axially from one side of one of said plates, a hollow boss on and extending axially from the other side of the last mentioned plate through the other plate which is carried by said boss, a perforated support to which said shank is secured and which is mounted in said combustion chamber, a vaporising tube secured at one end to said boss and extending into the combustion region of said chamber, an air duct leading to the end of said chamber adjacent to said nozzle, and an annular partition carried by said support and dividing said duct into two concentric parts, one of said parts leading to the region occupied by the nozzle, and the other of said parts leading into the peripheral portion of said chamber.
JOHN STANLEY CLARKE.
