A wood-gasifying boiler "ARCA Aspiro"

Wood-gasifying boilers with vertical reverse flame and modulation of burning "ARCA Aspiro" - Italy.

Efficiency: up to 87-89%. Based on the pyrolysis principle – gas distillation upon primary wood burning.

Thermal rate up to 174 kW.

Boiler ASPIRO operation is based upon the gasification technology applied to wood.

The solid fuel, stored in the upper collection chamber in contact with hot ashes in its bottom part, on the burner’s grate, releases combustible gazes which may be fired when mixed with the main air stream. This flammable compound is sucked through the slot existing in the bottom part of the wood collection chamber, where it will light producing the characteristic “reverse flame”.

The gasification principle, not allowing wood to burn directly as in any other classic arrangement but using instead the gazes released under high temperature conditions, allows a complete burning of the fuel which permits to get high thermal yield and a very low level of harmful emissions in the smoke released outside.

The burner chamber has a 8 mm thickness walls and has no welding in its upper part. The rear and front walls are protected by a refractory cement layer and they are not in touch with water (dry walls).
