Neglecting Proper Boiler Maintenance Can Mean Major Loss in Efficiencies

One problem you see with boilers in large institutions such as schools and universities is that cleaning and maintenance can be overlooked. This is often because boiler maintenance is not in the scope of work for HVAC maintenance staff and falls in the scope for the plumbing staff, who often don’t realize it’s part of their duties. It’s also often a misconception of staff that the highly intuitive controls that most new boilers have will prevent issues and send alerts when they occur, but controls are primarily responsible for boiler function boiler maintenance is still imperative for optimal operation. Otherwise, a boiler can sit for years, gathering scale and dirt that affects performance and can even cause premature malfunctions and breakdowns.

Boiler issues can be a real problem and they can happen quickly. For example, 

 

tests show that a soot layer just 0.8 mm (0.03 in.) thick reduces heat transfer by 9.5 percent and a 4.5 mm (0.18 in.) layer by 69 percent. As a result, the flue gas temperature rises – as does the energy cost. Scale build up on the water side of tubes, from deposits of calcium, magnesium, and silica found in water can also cause issues by insulating tubes and reducing heat transfer. Build up of soot and scale can happen in a few short weeks, so it’s easy to imagine how a boiler that has been neglected for months or even years can gather sediment that has major implications on performance and premature malfunctions.

The way to keep a boiler healthy and operating at its highest efficiency is to have regular maintenance performed on it. But maintenance also requires that tubes are cleaned properly to remove all the soot and scale buildup which can be difficult to remove. Goodway has fire tube and water tube cleaning systems that make removing even the smallest amount of scale and soot a snap. They have a variety of systems in various sizes that make it easy to clean any size or length of tube. They have tools that will brush out the scale and soot from the inside while simultaneously vacuuming loose particles from tubes, improving the efficiency of even the most neglected boiler. Additionally, chemical cleaning is a fast and effective way to remove water-based deposits like limescale from tubes.
