Efficiency and Cost Benefits of Controls Retrofits

By STEVE CONNOR, Cleaver-Brooks, Milwaukee, Wis.

One-third of a facility's energy bill can be directly attributed to the boiler room. Replacing an older boiler system is one way to achieve energy savings. Retrofitting is another. If retrofitting is the course of action, then it is important to identify the areas most likely to yield efficiency gains. The first area to consider is the combustion-controls system. New developments in boiler controls are creating opportunities for substantial efficiency gains. This article discusses options to help an existing boiler system produce measurable efficiency increases and fuel-cost decreases.
