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, […]

Hydronic Heating with Renewable Energy Heat Sources

Hydronic Heating with Renewable Energy Heat Sources
Designing for low water temperatures is critical to good performance
This article focuses on using water-based hydronic distribution systems to distribute heat produced by renewable energy heat sources. It’s based on the premise that good hydronic design is the “glue” that holds together nearly all thermally based renewable energy systems […]

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…
