Abstract

853,110. Liquid fuel burners. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. March 20, 1957 [March 26, 1956], No. 9313/56. Class 75(1). [Also in Group XII] In a gas turbine, the liquid fuel is applied to the surface of a rotating disc from which it is thrown off centrifugally as a liquid sheet, into the high velocity air stream from the compressor. The fuel is thus atomised and mixed with the air in the flame tube. A secondary air stream from the compressor passes between the flame tube and the turbine outer casing and part mixes with the combustion gases in the turbine and part flows back towards the flame tube inlet by a passage in the flame tube inner wall which is cooled thereby. The fuel spraying disc is slightly coned inwardly to cause the fuel to adhere by centrifugal force. As shown, the turbine 10, 12 is supplied from the flame tube 31 which receives air from the compressor 6, 8 driven by 10, 12 through shaft 14. The fuel is led into 31 from hollow shaft 23 through ports 45, 47, to the downstream surface of the disc 24. The latter rotates with 14 and the ports are dimensioned so that the fuel is thrown from the disc periphery as a sheet into the airstream at 36. Turbulence is increased by the paddles 51. The air flow from 6, 8 is divided by the flame-tube outer wall 32 into two annular streams, one through duct 35 and the other into 31. The inlet to 31 is divided by fingers 36, which may be shaped to meter the air-flow. The outlet from 31 is a number of channels 56 formed by corrugations spaced apart circumferentially in 32 to provide alternating passages which discharge streams of hot gas and air. The inner wall 33 of 31 is cooled by air pumped by fan 61 from 56 through holes 62, into passage 60. Specifications 853,108 and 853,109 are referred to.
