Wood Gasification Technology

The ORLAN EKO line of wood gasification boilers work by efficiently breaking wood down into superheated gases. These gases are then burned in the second stage of the process to produce heat. The process, known as pyrolytic wood distillation, offers three times the efficiency of traditional wood boilers.

Advantages of Wood Gasification Boilers

Rely on a renewable resource. Wood is a renewable resource just like solar, water, and wind.Wood is a fuel that may be stored without energy loss (dry storage of wood decreases its humidity and increases its heating value). Modern wood gasification boilers offer high efficiency (87%), three times the efficiency of tradition boilers.

Very low smoke and emissions make for an environmentally friendly heating alternative. Wood gasification boilers emit almost no smoke, and very small amounts of wood ash particulates, especially when compared to traditional stoves and boilers.

ORLAN boilers are adapted for burning any wood from wood chips to logs.

Wood Gasification – How it Works

Wood is superheated in a gasification chamber to break down the wood chemistry into its component gases. The process uses high amounts of heat, and restricts the air injected into the chamber to first produce charcoal which then breaks down into gas.

The released gases move into a secondary chamber (combustion chamber) to combine with air and burn cleanly at a high temperature (up to 2000 ºF). This stage produces large amounts of desired heat.

In the last stage, the remaining exhaust gases are piped through a heat exchanger to extract the heat and keep efficiency high. A small amount of remaining exhaust gases exit a smoke stack.
