DEVICE FOR CLEANING BOILER HEATING SURFACES FROM ASH AND SLAG DEPOSITS

摘要

FIELD: metallurgy. ^ SUBSTANCE: device for cleaning boiler heating surfaces from ash and slag deposits includes cooling agent supply tube with mechanisms of its supply and rotation; nozzle head with a nozzle is installed on the end of supply tube. The new is connection of nozzle head by means of hollow axis with possibility of rotation about attachment axis to side surface of supply tube; inner cavity of the latter is connected to inner cavities of axis and nozzle head; nozzle is made on end of nozzle head, and rotation of nozzle head is performed with control mechanism located inside supply tube. Length of nozzle head does not exceed the length of retractable section of supply tube. Control rotation mechanism of nozzle head 4 is made for example in the form of worm wheel 7. ^ EFFECT: device provides high operating reliability of all its assemblies at high temperatures inside furnace chamber. ^ 3 cl, 3 dwg
