Abstract: Liquid fuel, particularly slurry-type fuel, such as coal-water, slurry or coal-oil slurries, is atomized by bringing the fuel into contact with gas under pressure in an atomizing nozzle (1). To this end, a continuous stream of fuel is passed through a channel (17) of circular cross-section. The stream of fuel is accelerated in the channel, adjacent the outlet end of the nozzle, and is preliminarily disintegrated by means of at least one first stream of gas under pressure directed inwardly against the outside of the fuel stream. The fuel is finally atomized by directing at least one second stream of gas under pressure outwardly against the inside of the accelerated and preliminarily disintegrated fuel stream, substantially immediately after said stream exits from the nozzle.
