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
We've been talking about how important it is to perform annual maintenance on your clients' equipment. Boilers, as you know, are subject to wear and tear. They need adequate maintenance, to ensure that they don’t break down. If they do, it's usually at a very inconvenient time and it makes you look bad to your customers. Waiting until something breaks down before repairing and maintaining it, always ends up costing you
Need help with obsolete parts for your heating and cooling equipment?
It’s frustrating when you can no longer get the parts needed to repair your equipment. With all of the energy and environmental regulations coming out of Washington these days, manufacturers are constantly required to update technologies and efficiencies with their equipment, and sometimes something that’s less than five or ten years old has become “obsolete” for the manufacturer. The decision of whether to buy new or repair existing can be
