Abstract
A method and an appliance are described for atomizing liquid fuel for a firing installation, preferably for a combustion chamber of a gas turbine installation, having a nozzle arrangement through which the pressurized liquid fuel passes and is atomized to form a fuel spray. The invention is characterized by the fact that after the passage of the fuel through the nozzle arrangement ( ), at least two, spatially separated fuel sprays ( ) are formed in which the fuel is mainly present in the form of individual fuel droplets ( ), and in that the fuel sprays ( ) each have a propagation direction relative to one another such that the fuel droplets ( ) of one fuel spray ( ) collide with the fuel droplets ( ) of the other fuel spray ( ) in such a way that, during the collision of the fuel droplets ( ), a droplet cloud ( ) is formed with new fuel droplets ( ) whose diameter is smaller than that of the colliding fuel droplets ( ).
