How does gasification work in your outdoor wood furnace? Learn what it is and how the gasifying process provides heat with a wood gasifier boiler system.

Fröling wood gasification boilers are the high-performance standard of wood heating. Through advanced combustion engineering, they achieve cleaner burns, higher heat output, and far less wood waste …

This demonstration shows the outdoor wood furnace secondary combustion chamber in operation. Preheated air enters the chamber to ignite gases through the gasification process, creating a high …

Mar 31, 2026 · The furnace has an adjustable, computerized control burn that monitors the fire and allows logs to burn from the front to back under a controlled rate. The control of this burn results in …

By forcing a downward flow of gas into a second combustion chamber, these boilers produce cleaner, and more cost-effective, thermal heat, which yields far more energy per pound of wood that’s burned.

The Portage & Main range of products include Ultimizer wood and coal models, auto-feed coal/pellet burners, automated wood chip burning systems and a line of EPA approved gasification boilers. We …

Gasification is a big word that means the capture and burning of wood gas, aka smoke. Smoke and creosote are unburnt fuel; not to mention, they pose a risk for fire and your health. These wood …

Jun 3, 2025 · This highly rated furnace uses a secondary combustion chamber called Vor-Tech to achieve the burning of smoke and other gases that would otherwise be lost out the flue.

Dec 22, 2025 · The core of the log boiler’s efficiency is the gasification process, which begins with a phase known as pyrolysis. In the primary fuel chamber, wood is subjected to high heat in an …

Indoor gasification boilers designed for years of quality, maintenance free service. The key to efficient and clean wood burning is a long turbulent flame path that does not cool until the fuel burn has …
