Abstract
A double annular combustor for a gas turbine engine is provided with annular arrays of main and pilot fuel injection modules. The main fuel injection modules are of the premix type so as to vaporise fuel. However, the pilot fuel injection modules are configured so as to function as both premix and airspray fuel injectors. During starting and low power conditions, the pilot fuel injectors are operational alone in their airspray mode. However during high power conditions, both the main and pilot fuel injection modules function as premix injectors. The arrangement reduces noxious emissions.
