Boiler Water Treatment Systems
Standard and Custom chemical feed systems for boiler room applications.
Among other products dedicated to servicing boiler water blowdown, Madden Engineered Products also offers chemical feed system skids designed specifically for boiler water treatment applications.
Where the ability to help design and build custom chemical feed system skids from scratch can be useful in industrial applications as a whole, we have found that presenting our standard specifications for a boiler water treatment feed system is the best place to start for boiler room applications. Documents for new boiler room projects are often lacking in detail when it comes to the chemical feed system section. Our pre-engineered design is intended to give engineers and end users confidence that the basics are all accounted for and any additions to the skid are simply desired upgrades.
With over 65 years’ worth of experience designing and manufacturing boiler blowdown heat recovery systems, boiler blowdown tanks, and custom chemical feed systems, Madden Engineered Products has naturally made its way into boiler water treatment as well.
Over the years we have been approached more and more by end users, engineering firms, and even boiler manufacturers to be the source for their boiler chemical feed system needs.
Common Boiler Water Treatment Chemicals: Amine, Phosphate, and Oxygen Scavengers
Oxygen scavengers, phosphates, and amine all work together to keep the water source free of oxygen, they neutralize acidic water, and act as a corrosion inhibitor. Here are the common products used to add these chemicals to the boiler process:
- (2 – 3) Low Density Polyethylene tanks, or occasionally 316 SS tanks
Madden uses tanks with cone or bell bottoms so that they are self-draining as well as provide flooded suctions to the metering pumps.
- (2-3) Chemical metering pumps
The Madden metering pump designs can dose into systems operating up to 300 PSI. For systems needing to dose directly into high pressure boilers, we can provide high pressure pumps as well.
- (2-3) High speed mixers to agitate the boiler water treatment chemicals. This set up allows you to make much larger batches than purchasing pre-mixed 55 gallon drums.
With the ability to mix your own chemicals to whatever concentration, this allows for you to use smaller/slower, less costly metering pumps for the system. Instead of buying huge tanks and pumps to dose the appropriate amount of oxygen scavenger or phosphate into the D/A tank or boiler water feed line, consider a system like ours that allows you to choose the concentration of chemical in the holding tanks.
For most boiler water treatment applications, this ability allows us to design a system with 75-100 gallon tanks with pumps designed with max outputs of 2 GPH.
Standard and Generic Boiler Feed Water Treatment Chemical Feed System
As mentioned before, Madden now has a focus on offering a standard chemical feed system design intended on being the starting block for boiler water treatment feed systems on any new boiler room project. Here’s how this came about, and a bit more on our design:
After an explosion in requests for specifically boiler water treatment feed system in 2017, we decided to converse with some of our more experienced distributors to come up with a standard boiler water treatment chemical feed system, that would cover a broad range of normal boiler room set ups. These industry connections helped us consider all angles of a chemical feed system in the boiler room, from materials used, to sizing tanks and pumps, all the way to considerations for the boiler operator. Their experiences and knowledge, combined with our own, allowed us to come up with a simple, durable chemical feed system for boiler water treatment that covered all the basics.
