A central heating boiler comprises a body containing flow-interconnected water chambers in the walls. In a front wall (1) of the boiler there is a fuel charging opening, an opening with a bottom door (7), whereas below a grate (8) there is an opening with an ash pit door (9). In the upper part of the interior of the boiler a heat exchanger is arranged. In the vertical wall (1) of the boiler there is an air inlet to a furnace chamber (12). Inside the furnace chamber (12) there is at least one horizontal partition (16) connected with the vertical wall (1) of the boiler, and a vertical partition (19) which is situated in a plane parallel to the wall (2) of the boiler. Between the vertical partition (19), and the wall (2) of the boiler there is a flue gas after-combustion chamber (20). A flue gas inlet to the vertical after-combustion chamber (20) is arranged within a bottom edge (21) of the vertical partition (19), in the zone adjacent to the boiler grate (8). |
