Active Matter: 

Oily deposits in steam boilers are a result of oil contamination of the feed water. Most often, the source of the oil is some part of the condensate and return system. Fuel oil and cargo oils may contaminate the condensate via leaks in the oil heaters or tank heating coils. Lubricating oils may be picked up from steam driven machinery. Oil deposits can be removed from boilers, L.P. steam generators, etc., by circulating a 2-5% solution of Heavy Duty Cleaner (Emulsifier) through the equipment. Heavy Duty Cleaner (Emulsifier) should never be used as an on-line cleaner. All cleaning should be done off-line. For maximum cleaning efficiency, the cleaning mixture should be heated to 50° - 60°C (122° - 140° F) and maintained at this temperature during the cleaning operation. If adequate heat is not available, effective cleaning can be accomplished at temperatures as low as 25° C (77° F) using additional time. Carbonized oil or coke may require a two-step cleaning process using FOTTM fuel oil treatment followed by Heavy Duty Cleaner (Emulsifier)

  • Circulate water through the system for a minimum of 4 hours.
  • After 4 Hours cool to normal draining temperatures. Drain the system and refill with warm water to prevent thermal shock. Recirculate for 1-2 hours. No heating is required during this circulation period. Be sure to overflow the system through the expansion tank to the bilge.
  • Drain the cooling water system and wherever possible, inspect the interior. If the system is not completely free of oil, repeat the above procedure.
