Wood/Biomass Gasification Boilers

A Wood/Biomass Gasification Boiler is an excellent heating solution for rural properties with a plentiful supply of cheap/free seasoned firewood.

The Domusa Lignum IB boiler is a downdraft gasification boiler based on the combustion of gas generated by wooden logs.

The Lignum IB is an inverted burning boiler, the main advantages of which include:

  • High energy efficiency enabling lower consumption;

  • Load autonomy of up to seven hours;

  • The boiler fan modulates by adjusting power generated to what is required;

  • Safety due to a cooling system that counters overheating;

  • Compliance with all applicable safety and emission standards;

  • The high grade materials used in its manufacture ensure a long lifespan.

Ecologically Clean Heat

Wood logs are an ecological alternative to traditional fossel fuels. In wood combustion the amount of carbon dioxide released is the same as what is produced during the wood decomposition cycle. There is no change to the cycle that maintains carbon dioxide equilibrium in the atmosphere. Wood combustion is therefore neutral regarding the main agent responsible for advance of the greenhouse effect.

The Lignum IB comes in three different output sizes (20, 30 and 40 kW) and has the following features:

Electronic modulation
The boiler is equipped with an electronic control that makes the different control options clear and easy to use.

Protection against overheating
The boiler is equipped with a safety system that utilises tap water to prevent overheating.

Automatic switch-off due to fuel consumption
If the smoke temperature sensor detects an absence of temperature in the smoke outflow for a prolonged period, the fan stops, extinguishing the flame to prevent heat loss.

Energy efficiency
The gases generated in the combustion chamber leave at a temperature of 1,000°C and move through a system of retarders that reduces their temperature to below 160°C, lowering consumption and increasing the boiler's load autonomy.

Load autonomy
The boiler's high efficiency along with the burn chamber's substantial volume mean autonomy of up to seven hours can be achieved. This autonomy logically depends on the size of the boiler with respect to the power required.
