Abstract:
1. A cryogenic fluid delivery system, comprising: a vessel containing a cryogenic fluid at a first pressure and a first temperature; a first heat exchanger coupled to the vessel for receiving the cryogenic fluid and cooling the cryogenic fluid to a second temperature, wherein the first heat exchanger includes a first automated level controller for automatically controlling a level of the cryogenic fluid within the first heat exchanger; a first pump coupled to the first heat exchanger for pressurizing the cryogenic fluid to a second pressure; a second pump for pressurizing the cryogenic fluid to a third pressure; a second heat exchanger coupled to the second pump for cooling the cryogenic fluid to a third temperature, wherein the second heat exchanger includes a second automated level controller for automatically controlling a level of the cryogenic fluid within the second heat exchanger; and a nozzle coupled to the second heat exchanger for delivering a jet of the cryogenic fluid toward a target.
