The furnace with reduced smoke generation contains a base and external walls made of non-combustible material. The walls form a blower chamber, in the end part of which there is a blower window, outside of which a blower door is mounted. A grate is mounted at the top of the ash chamber, on top of which a combustion chamber is formed, in the end part of which there is a combustion window, outside of which a combustion door is mounted. In the upper part of the combustion chamber, a combustion vault with a hole is formed, along the perimeter of which a middle chimney is formed, on top of which an afterburning chamber is formed. In the end part of the afterburning chamber there is an afterburning window, outside of which an afterburning door is mounted. In the upper part of the afterburning chamber, an afterburning vault with a hole is formed, along the perimeter of which an upper chimney is formed. The area of the opening of the blower window is not less than the area of the opening of the middle chimney. The opening area of the middle chimney is no more than 2/3 of the opening area of the upper chimney. The horizontal projections of the blower, combustion and afterburning chambers are the same, the volume of the afterburner chamber is at least 2/3 of the volume of the combustion chamber, the area of the afterburner window opening is not less than 1/3 of the opening area of the blower window.
