The 3WOOD Design

The 3WOOD Boilers are hot water generators that operate by combustion of hard wood or soft coal. They feature a high quality and extremely thick ASME class 20 cast-iron body, protected by high-density insulation that limits heat loss.

The large heat exchange surface and the fins in the flue gas path ensure exceptional resistance to corrosion and very high efficiency that remains constant over time (self-cleaning effect).

The combustion chamber and the upper door for loading the wood are sufficiently large to maximize the burn time and limit the number of times the door needs to be opened for refueling.

The front air grille for secondary air in the upper door and the flue gas damper are easily adjusted for tending the fire.

Secondary combustion chamber

Technology with 3 Pass:

1st Pass

The combustion chamber gasses are carried by a special passage in the rear element. In the same area, very hot secondary air is combined with combustion gases which enhance their oxidation.

2nd Pass

The gases from the rear element are reburned in the secondary combustion chamber, 3rd Pass

The third Pass consists of a wide-finned, self-cleaning zone which directs the smoke towards the flue attachment with adjustment shutter and door cleaning.
