摘要
FIELD: thermal engineering. SUBSTANCE: ball-type cleaning system for steam-turbine condenser connected to delivery and discharge cooling water circulating conduits has charging chamber for balls and tank with corrosion inhibitor for their impregnation before passing them to tubes to be cleaned, vacuum pump (water-jet ejector), and two pipings equipped with shut-off valves which provide communication between charging chamber and tank incorporating vacuum pump. In operation, system accumulates balls in chamber, creates vacuum in the latter by means of pump, impregnates balls with inhibitor taken from tank, and ejects all balls from chamber to delivery water conduit. Cycle is repeated until stable film is formed on inner surfaces of tubes. EFFECT: improved cleaning of tubes. 3 cl, 2 dwg
