Abstract:
A fuel lance for a burner of a combustor has a fuel lance body defining a fuel flow passage and a liquid fuel tip attached thereto and in flow communication with fuel flow passage. The liquid fuel tip has a fuel outlet and an array of air passages having outlets which are arranged outside a blank sector of a circumference around the fuel outlet, the blank sector defined by an angle from 30° to 160°. A burner includes the fuel lance and the igniter and a main air flow passage to direct at least a part of a main air flow over the fuel lance and over the igniter, the blank sector has a centre-line angled between +120° and −120° from a radial line from the axis and passing through the fuel lance. A method includes rotating the fuel lance between a start-up condition and a second condition.
