Fluid nozzle and method of introducing a fluid

Abstract

According to one embodiment, a nozzle for introducing a fluid comprises a first conduit having a first end and a second conduit having a second end. The second conduit is disposed substantially concentrically with the first conduit. The first end is offset from the second end. A third conduit having a third end is provided with the third conduit being disposed substantially concentrically with the first conduit and the second conduit and the third end being offset from the first end and the second end. Another embodiment provides a method wherein a first fluid conveying conduit, a second fluid conveying conduit and a third fluid conveying conduit are provided. The second fluid conveying conduit substantially surrounds the first fluid conveying conduit and the third fluid conveying conduit substantially surrounds both the first fluid conveying conduit and the second fluid conveying conduit. A first fluid flows through the first fluid conveying conduit. A second fluid flows through the second fluid conveying conduit. A third fluid flows through the third fluid conveying conduit. Both the second fluid conveying conduit and the first fluid conveying conduit are substantially simultaneously cleaned.
