ABSTRACT:
The invention reads on a heating boiler for solid fuel, comprising a combustion volume with fuel feeding aperture, air entry apertures and chimney flue, and a water volume, the latter bordering on said combustion volume by mediation of convection plates. As taught by the invention, the boiler comprises air guiding elements for guiding the combustion air substantially across the combustion volume so that the point of air entry moves with time from one point in the combustion volume across the combustion volume for burning the fuel in the combustion volume zonally. The air guiding elements may consist of air entry apertures provided in the wall, disposed in a row across the combustion volume, and they may incorporate closing members for consecutively opening and closing the apertures e.g. with the aid of a governing apparatus from one margin to the opposite margin of the combustion volume. The air guiding elements may comprise an air inlet tube disposed to swivel or alternatively move in translation over the combustion volume.
