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, […]

Wood Gasification Boilers: Circulation, Power Interruption & Pump Acceleration

On the Hydronic-Based Biomass Heating Systems Discussion Board…
Why we don’t use the UPS to drive the main circulator to continue operations in case of power interruption? What determines when wood gasification boilers begin to circulate? Do variable speed pumps allow us to control the rate at which the pump accelerates? John Siegenthaler investigates…
