Abstract
A fluid jet nozzle for a decoking tool, a decoking tool and method of operating same. The nozzle includes a nozzle assembly for use in a fluid jet decoking tool. The assembly includes a housing to hold one or more nozzles that are used to spray or otherwise distribute decoking fluid. An internal flowpath that extends from an inlet of the nozzle to an outlet of the nozzle defines a tapered shape such that when the decoking fluid passes through the nozzle, the flowpath produces a predominantly coherent flow pattern in the fluid.
Claims17
A method of passing a decoking fluid through a nozzle assembly, said method comprising:
- configuring the nozzle assembly to comprise a housing defining a decoking fluid conduit therein, said housing comprising a cutting nozzle and a drilling nozzle such that said cutting nozzle is fluidly cooperative with at least a portion of said conduit and said drilling nozzle is fluidly cooperative with another portion of said conduit;
- configuring at least one of the following of said cutting nozzle and said drilling nozzle to define an internal flowpath therein with an inlet, an outlet and a curvilinear tapered shape that converges along an axial length from said inlet to said outlet such that an axial dimension of said flowpath is less than two inches in length and a radial dimension of said flowpath is less than two inches in diameter;
- and
- providing said decoking fluid to at least one of the following of said cutting nozzle and said drilling nozzle.
A method of operating a fluid decoking tool, said method comprising:
- receiving a pressurized decoking fluid from a source;
- selectively passing said received decoking fluid through a nozzle assembly that forms a part of said decoking tool, said nozzle assembly comprising:
- a housing defining a decoking fluid conduit therein, said housing comprising a cutting nozzle and a drilling nozzle such that said cutting nozzle is fluidly cooperative with at least a portion of said conduit and said drilling nozzle is fluidly cooperative with another portion of said conduit, wherein at least one of the following of said cutting nozzle and said drilling nozzle defines an internal flowpath therein with an inlet, an outlet and a curvilinear tapered shape that converges along an axial length from said inlet to said outlet such that an axial dimension of said flowpath is less than two inches in length and a radial dimension of said flowpath is less than two inches in diameter;
- and
- providing said decoking fluid to at least one of the following of said cutting nozzle and said drilling nozzle.
