METHOD OF CLEANING INNER SIDES OF HEATING APPARATUS FOR CENTRAL HEAT SUPPLY SYSTEM

摘要

FIELD: heat supply systems. ^ SUBSTANCE: method comprises supplying pulses of pressurized air and discharging contaminated liquid. The heating apparatus to be cleaned is connected with the air hydraulic pulse unit through flexible hose. The compressed air pulses are generated in the air receiver by means of gradual opening of the valve that is spring-loaded and has varying area of the cross-section. As a result, the expanding air is intensively mixed with water thus removing contaminations from the surface of heating apparatus. ^ EFFECT: enhanced efficiency and reliability. ^ 3 dwg
