Boiler Introduction | CleanBoiler.org

Boilers have a certain efficiency curve that tends to result in the boiler having the highest efficiency at full-fire. As the boiler is 'turned-down' to run at less than 100% capacity, efficiency typically drops. To counter this situation, a modular boiler bank of 3 or more boilers with a programmed controller can improve operational
