Date May 18, 1989.The invention relates to a combustion device in which preferably liquid fuel is supplied to nozzle (11,14;11',14') belonging to a burner (1) in order to be mixed with a stream of combustion air after passage of the nozzle, whereafter the fuel air mixture is ignited and burnt in a combustion room (20), the device being of that kind in which the combustion air is conducted through an annular channel (16;16') surrounding the nozzle (11,14;11',14'). The invention is characterized in that the fuel channel (12;12') of the nozzle (11,14;11',14') communicates with the air channel (16;16') by a number of holes (13;13') which debouch at the side of the nozzle (11,14;11',14'), and that the air channel (16;16') in the area of the holes (13;13') has an annular cavity for forming a whirl channel (18;18') for the fuel air mixture.
