Abstract
Combustion equipment e.g. for a gas turbine engine comprises an annular flame tube having air inlet openings fitted with respective air swirler devices surrounding respective fuel atomizers. Flare portions define an annular flare in which the atomizers and swirler devices are provided. To reduce the formation of a liquid fuel film on the wall of the flame tube, dividing means in the form of a smaller flare is provided for dividing the air flow through each of the swirler devices so as to create a fuel-free film of air adjacent the annular flare.
