Nozzle for injection cooler for hot steam - has central channel for conveying cooling water and surrounding ring channel for feed of sprayed steam

摘要

The ring channel (13) ends at the outlet in individual holes (19, 23) which issue into an eddy chamber (20) which at its end is provided with outlet holes (21). The holes of the ring channel run at an angle to the longitudinal axis of the nozzle (2) and the axis of a hole in the ring channel intersects that of a hole (23) of the central channel (14) downstream. The central channel is closed by an arched cover (22) in which downstream from the holes (19) of the ring channel (13) the holes (23) of the central channel (14) are arranged radially. ADVANTAGE - A high degree of atomisation cooling of the hot steam is achieved in a narrow space.
