摘要

A nozzle for atomising a liquid by means of a gas comprises a mixing chamber ( 1 ), one or more liquid inlets ( 6 c) and at least one tangential gas inlet ( 5 ) to the mixing chamber. An outlet ( 4 ) is positioned at the downstream end of the mixing chamber ( 1 ). A centre body ( 2 ) having a generally converging configuration, seen in the flow direction is provided in the mixing chamber ( 1 ). The liquid inlet ( 6 c) or inlets is/are positioned at or near the upstream end ( 3 a) of the mixing chamber ( 1 ) and in the upstream direction with respect to the gas inlet ( 5 ) or inlets.
