Having corrosion issues in boilers? Not a concern anymore – Know how to resolve

A boiler serves as a device for generating steam, which comprises of two principal parts: the furnace which accounts for the heat generation, usually by burning a fuel, and the boiler proper, a device in which the heat brings about the change of water into steam. The steam or hot fluid is then recirculated out of the boiler to be used in various processes in heating applications. The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water).

Feed-water composition depends on the quality of the make-up water and the amount of condensate returned to the boiler. Proper treatment of boiler feed water is a critical part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. These results in poor heat transfer and alleviate the efficiency of the boiler. Dissolved gases such as carbon dioxide and oxygen will react with the metals in the boiler system and brings about corrosion within the boiler.

Herein comes the role of NALCO 7208 that serves as a Boiler Water pH Booster manufactured by Nalco Company. Now, to understand what exactly is the role of this product in corrosion inhibition, we need to first know what corrosion actually is.

Corrosion of boiler is regarded as the deterioration of metal parts of the boiler by chemical or electrochemical reaction with its environment. Corrosion products that are formed in the boiler or transported to the boiler can deposit and impede heat transfer, causing tube metal overheating. In order to provide protection to the boiler from these contaminants, they should be controlled or removed, through external or internal treatment.

One such treatment for preventing the corrosion of boiler involves the pH booster chemical treatment. Proper maintenance of pH value in the boiler feed water helps in protecting the boiler internals from corrosion. When the pH value is not within range, then a boiler water pH booster chemical can be administered to it, to achieve the desired pH level. Nalco Company formulated pH booster chemical product Nalco 7208 effectively precludes corrosion.
