Scale and corrosion can compromise the efficiency of industrial boilers, but they can be controlled by optimizing feed water with reverse osmosis.

Fluence reverse osmosis-based boiler optimization prevents processes that lead to inefficient operation

Industrial boilers are the backbone of many manufacturing processes, providing essential steam and heat. However, they often face formidable adversaries: scale and corrosion. These issues not only compromise boiler efficiency but also incur significant maintenance costs. In this post, we’ll delve into the challenges posed by scale and corrosion, explore various solutions — including chemical and membrane-based approaches — and highlight how Fluence’s boiler optimization solutions offer a cost-effective remedy.

The Challenges of Scale and Corrosion

Scale is the buildup of substances, primarily minerals like calcium and magnesium, that form a thick, chalky layer on boiler surfaces, reducing heat transfer efficiency and potentially leading to overheating and equipment failure. Water sourced from cities or wells often contains high levels of dissolved solids and minerals that can lead to scale problems, so it’s important to focus on the prevention of scale formation in boilers before it happens.

Corrosion is the formation of an oxide on metal through interaction with an oxidant such as water, hydrogen, or hydroxide. Corrosion can eat away at boiler components, weakening structural integrity and increasing the risk of leaks and ruptures. Both scale and corrosion can result in costly downtime, repairs, and even safety hazards.

Chemical Solutions

Traditionally, chemical treatments have been used to mitigate scale and corrosion in industrial boilers. These treatments involve the use of various inhibitors and dispersants to control scale formation and protect metal surfaces from corrosion. While effective to some extent, chemical treatments require careful monitoring and precise dosing to ensure optimal performance. Also, they can be expensive and may introduce environmental concerns due to the use of potentially hazardous chemicals.

Additionally, cathodic protection methods can be employed to prevent corrosion by making the boiler metal surfaces the cathode of an electrochemical cell. This technique is often used in combination with chemical treatments to provide a more comprehensive corrosion prevention strategy. However, cathodic protection can have downsides, such as the initial installation cost and the ongoing need for maintenance and monitoring to ensure the system is functioning correctly. Moreover, if not properly managed, it can lead to hydrogen embrittlement, which can weaken the metal and potentially lead to failure.

Membrane-Based Solutions

Reverse osmosis systems use semipermeable membranes to remove dissolved minerals and impurities from water, preventing scale formation and reducing the potential for corrosion. By using reverse osmosis to treat boiler feedwater, industrial facilities can effectively combat scale and corrosion to ensure optimal boiler performance, minimize maintenance costs, and prolong equipment lifespan. Reverse osmosis is not only a highly effective treatment method, but it also reduces an operation’s chemical usage.
