ABSTRACT:
An expansion nozzle adapted for use in high pressure, high temperature conditions. The expansion nozzle uses spring compression to operate under constant pressure conditions to efficiently flash hot water into steam. A motor can be employed to automatically adjust the extent of compression of the spring during the flashing operation, to thereby adjust the pressure of the liquid applied to the nozzle. In addition, the expansion nozzle can be equipped with a mechanism to allow cleaning or lapping of the orifice surfaces without disassembly of the expansion nozzle assembly.
