Abstract
There is provided a burner for a gas turbine engine, the burner comprising a radially inner pilot fuel flow passage surrounded by a radially outer main fuel flow passage. The main fuel flow passage is interposed between concentrically arranged radially inner and radially outer air flow passages. The inner and outer air flow passages are in fluid communication with one another via at least one diverting passage at an upstream end of the burner. The burner further comprises at least one control duct connectable to a reduced pressure/vacuum source for selectively reducing the air pressure in the vicinity of the diverting passage such that air flow is selectively diverted from the inner air flow passage to the outer flow passage via the diverting passage.
