Abstract (en)
[origin: EP0964202A2] The wood-fired boiler has a direct feed of primary (9) and secondary (10) air, through channels (4), at the lower end of the filling shaft zone and close to the flames and the ash extraction. The log combustion is concentrated and maintained at the lower end of the filling shaft (3). The filling shaft walls (8) are thin, with a suitable total surface insulation (12), to prevent heavy masses building up in the combustion zone. Charcoal formed at the lower section of the filling shaft is preserved by an airtight closure of the primary air feed (6), to be left in place for an emission-free relighting of the boiler.
