Boilers & Closed Loops
Feedwater Analysis: The program begins with a detailed analysis of the source water. This analysis dictates the specific treatment methods required.
External Water Treatment: This is the first line of defense, treating water before it enters the boiler. The most effective external treatment is ensuring your feedwater maintains a high temperature, limiting dissolved oxygen in the feedwater.
Internal Chemical Treatment: Chemicals are added directly to the system to manage any remaining impurities. These chemicals serve specific functions:
Corrosion Inhibitors: Nitrite and molybdate are corrosion inhibitors that work by creating a passive protective film on the metal surfaces of a boiler and closed loop piping. This film acts as a barrier, preventing corrosive substances like oxygen and water from reacting with the metal.
Oxygen Scavengers: Chemicals like sodium sulfite or hydrazine react with and eliminate any remaining dissolved oxygen to prevent corrosion.
Blowdown Control: This is the process of periodically draining a small portion of the boiler water. The purpose is to remove concentrated solids and sludge, preventing them from building up and causing scale or carryover.
Chemical Feed: Automated feed systems are used to maintain precise control and provide daily treatment rather than once a month slug doses. YOUR BOILER GETS FRESH WATER EVERYDAY, SO IT REQUIRES FRESH CHEMICAL EVERYDAY!
Your entire system gets treated on a daily basis with this configuration. If your current company only adds chemical to the boiler once a month......They're neglecting the treatment of your feed tank and your boiler. By using the method below, every time your boiler calls for water....IT WILL GET CHEMICALLY TREATED WATER!
