Abstract (en)
[origin: EP0268432A2] An atomizing nozzle assembly is provided having an outwardly diverging frustrum of a cone shaped, deflector core (1) of wear resistant ceramic, a nozzle rim (8) of wear resistant ceramic encircling the core and coextensive with a downstream portion thereof to form a mixing zone (16) therewith for receiving liquid-to-be-atomized therein from an unobstructed passage (56) and atomizing fluid directing the liquid-to-be-atomized away from the core. The mixing zone leads to a nozzle orifice outlet (18). The core is mounted in a core holder (20) and is adjustable by a screw thread, in close proximity to the mixing zone, to adjust the width (W) of the mixing zone, and the liquid-to-be-atomized (e.g. a coal slurry fuel) and the atomizing fluid (e.g. air) are fed along coaxial tubes (72,68) which are slidably mounted by glands (106) to accommodate differential expansions. With this combination it is possible to set the width of the gap between the deflector core and the nozzle rim even before the operating temperature is reached, because negligible changes in this width will occur due to differential expansions between the nozzle components. Furthermore, accommodating differential thermal expansions by the slidable glands avoids any damage occurring to the ceramic parts due to differential thermal expansion.
