Abstract
The invention relates to fuel burners and the combination of fuel burners and annular combustion equipment particularly for use in gas turbine engines. The present invention seeks to provide a fuel burner that requires a relatively small access hole in the engine casing in order to reduce stress concentrations in the casing. The fuel burner comprises a fuel feed arm and a fuel injector. The fuel feed arm and the fuel injector are cylindrical, and are arranged coaxially in end-to-end abutting relationship. The fuel feed arm has internal passages for the supply of fuel to the fuel injector, and the fuel injector has an air duct passing normally through the fuel injector for the flow of air into a cooperating combustion chamber. The fuel injector supplies fuel into the air duct to mix with the air flowing therethrough. The invention also provides combustion chamber equipment for use in conjunction with the fuel burners.
