Though you may never have heard the term “wood gasification,” it’s gaining popularity even though it’s an old process. Wood gasification is a clean, renewable way to use energy – not entirely unlike solar power and wind turbines. Wood gasification creates synthetic gas (syngas) from wood, which depends upon chemical reactions and sound engineer devices to facilitate these reactions.

With utility bills going through the roof in many cases, people are looking for alternate heat sources. Some people are choosing anthracite coal boilers. Then others prefer to use wood gasification boilers. You can find indoor furnaces and boilers in both varieties and outdoor furnaces and boilers.

If you’ve never heard of gasification, you might wonder how it works. Here we’ll explore gasification.

Gasification – What Is It?

Wood contains 8,600 BTU per pound, and the woods’ gases contain 60-70% of that energy. Gasification is the process of extracting that gas from the wood. That is a basic definition. A more in-depth explanation would be when a carbon-containing fuel (like wood) is put in a high heat environment (300-500F) with limited oxygen forcing the wood to emit syngas. It isn’t quite combustion, even though it sounds like it. Once we pull the gas out, you simply have nearly pure carbon remaining from what started as a piece of wood.

Wood Gasification, Specifically

Wood gasses indeed burn in all wood furnaces. We use a multistage downdraft process in our gasification system. We can control the fuel-to-air ratio for a more efficient, cleaner burn by using a downdraft process. Using well-seasoned wood works best for gasification.

The moisture content of your wood should be between 15% and 30% for a wood furnace to burn best. More creosote and tar buildup will result if you use wood with higher moisture content. You will also improve your wood boiler’s heating performance and efficiency by using well-seasoned wood.

Wood Gasification Boiler

The firebox is where the wood releases its syngas in a wood gasification boiler. The gasses travel downward and into the firebrick chamber below. Here is where the combustion happens. The wood gasses, including the smoke and a host of hazardous gasses, are burned up in the 1800 to 2000°F combustion chamber. We transferred the extreme heat into the boilers using our signature swirl chamber heat exchanger. The result is a cool, clean exhaust of mainly only water and carbon dioxide.
