DEVICE FOR PREVENTING AGAINST SCALE FORMATION

摘要

FIELD: heat power engineering. ^ SUBSTANCE: device comprises member closed from both sides with flanges and mounted at the end of wave guide. The inner space of the member has ring way rolled by the ball and nozzles for supplying compressed air. The nozzles for supplying compressed air are mounted on the branch pipe set inside the member. The flange are solid and tightly abuts against the member. One of the flanges is mounted for permitting movement along the branch pipe. ^ EFFECT: enhanced efficiency. ^ 2 dwg
