Abstract
A pressure atomizer nozzle comprises a nozzle body (30) in which is formed a turbulence and/or swirl chamber (39) and having a nozzle bore (33). At least one first feed channel (41, 41a) for the liquid (37) to be atomized connects to the chamber as a first feed stage for feeding said liquid (37) under pressure. At least one second feed channel (38) connects to the chamber as a second feed stage for feeding part of the liquid (37) to be atomized or for feeding a second liquid (37') to be atomized. The second feed channel feeds liquid into the chamber under pressure and with a swirl. The two stage pressure atomizer nozzle allows, for example, simple adaptation of the fuel spray cone angle to the respective operating conditions of a gas turbine burner.
