FIELD: engines and pumps.
SUBSTANCE: fuel atomiser for gas turbine engine contains a housing, a shaft, an annular casing embracing the shaft and an insulating air curtain. The housing is provided with the first and the second sections arranged along longitudinal axis. The second section of the hosing is connected to combustion chamber of gas turbine engine. There is a channel in the housing for liquid fuel located in circumferential direction around longitudinal axis. The shaft is located longitudinally from the first section of housing to the third section. The shaft includes a pipe for liquid fuel for its supply to the fuel atomiser. Annular casing embracing the shaft is located along the longitudinal axis from the first section to the third section. Insulating air curtain is formed inside between the casing and the shaft and contains an air layer.
EFFECT: preventing coking of liquid fuel.
