Abstract

PURPOSE: To enhance efficiency of nozzle by furnishing a through hole penetrating the nozzle throat wall to the wall of the expanded part and making the diameter of drops contained in the steam smaller.
CONSTITUTION: In a communication hole 10 bored in the nozzle body 11, a nozzle throttle part 12 is furnished formed by wall surfaces provided with such a taper that the diameter decreases by and by from the inlet 13 in the direction of two-phase flow of flxuid mixture composed of hot water and steam. A throat 15 is furnished in continuity with said throttle 12, and an increased diameter part 17 is provided formed by wall surfaces so taped that the diameter in the downflow of the throat 15 increases by and by toward the outlet 16. Through holes 18 are bared having its opening on the wall surfaces 12a, 17a of the throttle part 12 and the enlarged part 17 in such an arrangement that spacing is constant on a circumference which has its center concentric with the communication hole 10 as shown in the illustration attached.
