ABSTRACT:
A dual-fluid low pressure drop atomizer utilizes extended wear life material and comprises a nozzle head having a chamber therein for receiving a mixture of a first compressible fluid and a second fluid containing solids. The nozzle head also has an orifice therein communicating with and adjacent to the mix chamber for discharging jets of the mixture. The orifice and the mix chamber form an approximate right angle therebetween. An inner barrel is connected to the nozzle head at the mix chamber and supplies the first fluid to the nozzle head. An outer barrel is arranged around the inner barrel creating an annulus therebetween and is also connected to the nozzle head for supplying the second fluid to the nozzle head. Wear resistant material provided in the mix chamber reduces erosion within the atomizer head. A plurality of ports are provided in the nozzle head and communicate with the orifice for discharging a jet at a multiplicity of locations.
