What exactly is wood gasification you ask?

At Harvest, we employ a technology known as wood gasification to convert wood waste to renewable syngas. It’s a method of extracting clean energy from wood-based materials that produces electricity, heat and substitute natural gas.

Wood gasification is considered clean, efficient and economically viable. It leaves a small footprint and provides 20 times the heat transfer of traditional gasification systems, while offering greater fuel flexibility.

In an article by Troy Edwards titled The Wonders of Wood Gasification, the writer explained the process in the following steps:

1. Primarily, the wood is warmed through a gasification booth so that the wood chemistry will disintegrate into carbon monoxide and hydrogen. The procedure makes use of extensive heat and limited amount of air is introduced into the compartment to produce charcoal that then transforms into gas.

2. The formed gas now moves into another booth or the combustion chamber to be fused with air and burn at high temperature, and produces large amount of preferred heat.

3. Then, the remaining gases are then channeled out through a heat changer to remove the heat and keep the effectiveness high.

4. The remaining gases leave a smoke pile.

We crafted this diagram to do the same:

This clean, renewable method of combustion also reduces the amount of waste headed to area landfills, according to Edwards. And it does so without negatively contributing to air or land pollution.
