A functioning boiler is essential for keeping industrial operations running. It produces steam for use in a wide variety of heating applications, including but not limited to:

  • Heating domestic hot water.
  • Maintaining accurate temperatures in industrial processes.
  • Supplying comfort heating.

Whether your system uses steam or hot water to heat your facility, proper maintenance and prevention are critical for ensuring your commercial HVAC boiler runs well. See how investing in water treatment services can help you ensure your boiler works as it should.

How Commercial Boilers Work

A commercial boiler is a closed, pressurized system that uses either water or steam to heat your facility. These systems comprise burners, combustion chambers, heat exchangers, exhaust stacks and controls. Burners provide the flame to heat the boiler water. The combustion chamber is often made of steel, cast iron or another heavy-duty metal, and this is the location where fuel burns to create heat. During a heating cycle, a set of burners or electric coils generates heat, which transfers to the water through the heat exchanger. A heat exchanger allows the heat transfer from the burners to the water.

The water heats up until it boils and reaches its desired temperature. The hot water or steam then circulates throughout the building via a system of interconnected pipes, which heats the air. A series of pipes or ductwork distributes the air through your facility, keeping your team comfortable and empowering operation. Other gases then move through the exhaust stack — a series of pipes moving exhaust outdoors — to ensure worker safety. System controls allow you to adjust water temperature, fuel supply mixtures, internal pressure and ignition.

Common Issues With Steam Boilers

Like cooling towers, water boilers are susceptible to two main types of problems — corrosion and scale. These issues can cause serious damage to your heating system, which can drive up your operating costs. There are several other problems that can occur as a result of poor water quality, such as foaming and priming. Systems can also experience leaks or large amounts of sludge.

Read more about these issues below:

  • Scale: Boiler scale is a hard mineral deposit that builds up on your boiler’s heat transfer surfaces and reduces the system’s ability to heat efficiently. It forms when impurities like calcium, iron and silica precipitate from the water and concentrate on the metal surface. Once it hardens, the boiler scale acts as an insulator, which prevents the boiler from effectively transferring heat to the water. The buildup can also slough off the sides of the boiler, blocking water flow and potentially causing the system to overheat — or fail.
  • Corrosion: Corrosion occurs when metal oxidizes, which damages the surface and causes it to break down. Usually, corrosion is the result of oxygen-producing reactions between the metal walls of the boiler and the chemicals in the air or water. Over time, corrosion can spread and eat away at the metal surface, damaging the boiler’s sensitive inner mechanisms and causing operational issues. This erosion reduces the boiler’s efficiency, making it more costly to run and shortening its life span. Localized corrosion, or pitting, is the most harmful type of corrosion. Because it’s so highly concentrated in a small area, pitting often erodes the metal faster and leads to total part failure.
  • Foaming or priming: Foaming refers to the result of solids floating to the top of the water and foaming as the boiler water heats. These solid deposits reduce efficiency and can work through the system to cause more significant damage. Priming can result from mist and foam carryover that can cause salt crystal deposits to form, further reducing energy efficiency and operational function.

The Importance of Boiler Water Treatment for Your Industry

Whatever industry you operate in, keeping your steam boiler in peak condition is essential for maintaining operational efficiency and keeping operational expenses low. Additionally, preventive maintenance helps keep the people in your facility safe.

  • HVAC: Boilers used for heating must be well-maintained to prevent issues like corrosion, scale and microbiological growth. Keeping your HVAC boiler clean ensures your air is safe to breathe and your system remains operational.
  • Food processing: Temperature control is critical in the food and beverage industry, and even one hour of downtime can cause thousands of dollars in losses. Proper boiler maintenance and preventive care enhance your boiler’s ability to heat water efficiently, keeping productivity high.
  • Health care: Proper patient care is the chief concern of all health care facilities, which is why maintaining your steam boiler is so vital. Our chemical water boiler treatments can also help eliminate Legionella from your system, protecting patients from serious illnesses like Legionnaires disease and Pontiac fever.
  • Breweries: Even, efficient heating is critical for the brewing process — cleaning and maintaining your water boiler with the right chemicals and equipment can help extend your boiler’s life span and keep your brewery at peak productivity.
  • Manufacturing: HVAC boilers drive manufacturing processes, creating steam to ensure appropriate production temperatures. For example, the plastic sector relies on cooling towers for mold cooling, and water treatment can ensure tower efficiency while keeping plastic components and products sanitary.

Our technicians have extensive experience working with facilities in all of the above industries and more, so you can rely on us to design systems that make sense for your needs.

Our Boiler Water Treatment Equipment and Chemicals

Our arsenal of treatment chemicals and equipment helps us provide the best service to our customers. Here are two examples of how we’ll use those tools to clean your boiler.

To prevent the metal from oxidizing, we use sodium sulfite as an oxygen scavenger — a chemical that helps reduce or eliminate the oxygen levels in your feedwater. We also add various other water treatment products as needed to disperse particulates and precipitated crystals.

These chemicals prevent dissolved minerals from settling and forming corrosive deposits, which protects your boiler against pitting and thermal stress.

Part of our water treatment service includes a chemical treatment. We apply chemical solutions that react with and consume scale-forming minerals, which prevents them from concentrating into deposits.

Depending on your geographical location, we may also use water softeners — these chemicals remove calcium, magnesium and iron ions from water to prevent scale from developing.

We also incorporate blowdown into our treatment strategy, which involves deliberately draining feedwater flow at regular intervals to limit the concentration of scale-causing minerals. We then replace the blown-down water with lower-concentration water to keep the system running as needed.
