The Elbow Combustion Chamber

A description is given of the “elbow” combustion chamber, developed for use in the gas-turbine power plant designed and built for the United States Navy by the Elliott Company. This type provides extremely high heat-release rates which is an essential characteristic for gas-turbine applications. The fuel-oil-burning system which utilizes standard Diesel fuel-injection equipment has been developed to a high point of efficiency, and may be varied over a range from full load to 1/10 full load without material change in quality of atomization. The paper discusses in detail the air-flow characteristics, fuel supply, ignition and control devices, and analyzes the combustion-chamber performance-test data.
