  • SILENCER FOR A BLAST NOZZLE
    Publication number: 20240025016
    Abstract: A noise suppressed blasting system comprising: a source of blasting gas in a predetermined pressure range with abrasive particles entrained therein; a nozzle including a nozzle inlet for connection to the source of blasting gas, a nozzle outlet for emission of the blasting gas, a nozzle conduit from the nozzle inlet to the nozzle outlet including a throat therebetween with a ratio of area of the nozzle outlet to area of the throat selected to emit the blasting gas from the nozzle outlet to produce a supersonic jet; a silencer connectable to the nozzle, to receive the supersonic jet exiting the nozzle, the silencer comprising a body with a silencer conduit therethrough, the body being of sufficient length and diameter to cause a flow condition of the jet received from the nozzle outlet to be modified such that 1½ shock cells are created in a jet inside the silencer, no shock cells are created in the jet outside the silencer and a jet exits the silencer in the form of a core jet with an established turbul

  • THRUST REDUCTION SYSTEM FOR A BLAST NOZZLE
    Publication number: 20240009806
    Abstract: A blast nozzle thrust reduction blasting system comprising: a source of blasting gas in a predetermined pressure range with abrasive particles entrained therein; a nozzle including a nozzle inlet for connection to the source of blasting gas, a nozzle outlet for emission of the blasting gas, a nozzle conduit from the nozzle inlet to the nozzle outlet including a throat therebetween with a ratio of area of the nozzle outlet to area of the throat selected to emit the blasting gas from the nozzle outlet to produce a supersonic jet; a thrust reducer connectable to the nozzle, to receive the supersonic jet exiting the nozzle, the thrust reducer comprising a body with a thrust reducer conduit therethrough, the body being of sufficient length and diameter to cause a flow condition of the jet received from the nozzle outlet to be modified such that a zone of sub-atmospheric pressure forms adjacent a face of the outlet of the nozzle whereby a pressure differential arises between the zone of sub-atmospheric press
