Breaking Down Turndown in Commercial Boilers
One of our most trusted brands, Patterson-Kelley, provided us with this great explanation breaking down turndown in commercial boilers. Boilers are rated on thermal efficiency, which is simply the chemical energy added to the boiler, divided by the energy added to the boiler water. As more energy is transferred from the hot gas into the boiler water, the thermal efficiency increases and the temperature of the hot gas decreases. Turndown ratio
Turning up Turndown for Better Commercial Boiler Efficiency
As an owner or as a design engineer, you want to be sure that your boiler selection will operate at peak efficiency, under all conditions. Thermal efficiency is simply the chemical energy added to the boiler, divided by the energy added to the boiler water. As more energy is transferred from the hot gas into the boiler water, the thermal efficiency increases and the temperature of the hot gas decreases. Turndown
Video: How to perform annual maintenance on a boiler
