LIQUID COAGULANT - Boiler Sludge Conditioner
Description
LIQUID COAGULANT boiler sludge conditioner is a colorless, high molecular weight solution used in both medium- and low-pressure boilers (<850 psig or 60 kg/cm2) to prevent oil sludge deposits when feedwater becomes contaminated by oil. Dosing LIQUID COAGULANT conditioner to the boiler coagulates the oil droplets, causing these suspended solids to settle to the low points of the boiler where they are removed by blowdown.
Application and Use
Dosage: LIQUID COAGULANT boiler sludge conditioner is “slug-fed” at a dosage of 28 mls per day for each ton of water capacity. It must be dosed to boiler water that is maintained in an alkaline condition. For systems experiencing severe oil contamination, off-line cleaning is desirable. Consult your Drew Marine representative for chemical application in off-line cleaning. After the equipment is cleaned, dose LIQUID COAGULANT conditioner at a rate of 28 mls per day per ton of water capacity for two weeks or until complete oil removal is accomplished. If severity of contamination persists, the possibility of additional oil inleakage should be investigated and eliminated.
Feeding: LIQUID COAGULANT boiler sludge conditioner may be dissolved with other boiler treatment chemicals and fed directly to the boiler by means of a bypass pot feeder or suitable chemical injection pump. For lowpressure boilers, the solution may be dosed to the hotwell or the condensate return tank. LIQUID COAGULANT conditioner is not for use in highpressure boiler systems.
