<p>The boiler has a fire box to burn solid fuels, e.g. logs, coal, coke, briquettes, boxes, cardboard etc. The fire box is accessible via an aperture, closed by a door, pivoted up- and sidewards. The feed aperture (4) opens into the fire box (2) and into a flow-in chamber (3) for the flue gas channels (7), which open above the fire box. The upper section of the aperture is covered by a flap (6), which may be pivoted into the flow-in chamber, about a horizontal shaft (8), fastened to the fire box. The flap is fastened, so that it automatically returns into a closed position.</p> |
