Claim 28:
29. A non-transitory computer readable storage medium comprising program instructions stored thereon that are executable by a processor to perform the following operations for vapor blast cleaning tubes of a tube bundle comprising:
controlling a nozzle holder positioning system to conduct a tube engage operation comprising moving a nozzle holder in a third dimension to advance outlets of nozzles into engagement with inlets of a set of tubes of a tube bundle, the nozzles secured in the nozzle holder in a nozzle arrangement corresponding to an arrangement of the tubes of the tube bundle, the nozzle holder positioning system configured to move the nozzle holder and the nozzles secured therein relative to the tube bundle in a first dimension, a second dimension, and the third dimension to position the outlets of the nozzles into engagement with the inlets of the tubes of the tube bundle such that the nozzles are positioned to direct a cleaning fluid comprising a mixture of water vapor and media into the inlets of the tubes of the tube bundle while the inlets of the tubes of the tube bundle are engaged by the outlets of the nozzles to provide a vapor blast cleanse of the tubes of the tube bundle;
conducting a tube cleaning operation comprising directing cleaning fluid comprising a mixture of water vapor and media into the inlets of the set of tubes by way of the outlets of the nozzles engaged with the inlets of the set of tubes of the tube bundle; and
conducting a tube disengage operation comprising controlling the nozzle holder positioning system to move the nozzle holder in the third dimension to retract the outlets of the nozzles in the third dimension to disengage the outlets of the nozzles from the inlets of the set of tubes of the tube bundle.
