Sizing a Pellet-Fueled Boiler

Sizing a Pellet-Fueled Boiler
Bigger is NOT better
There are several types of boilers that can burn wood-based fuels. They include 2- stage wood-gasification boilers, wood chip boilers, and pellet-fueled boilers. Of these, pellet-fuel boilers come closest to mimicking the fully automatic operation of oil and gas- fired boilers. Modern pellet boilers can automatically load their fuel, […]
