ABSTRACT:
A furnace for consuming solid fuel, wherein a horizontal or slanting feeding plane is used to feed fuel into the fire chamber. The feeding plane is attached to a vertical or nearly vertical channel surface, against which the fuel is pressed either with special feeding apparatus or by utilizing the force of gravity. Primary air is led into the lower part of a channel surface after which it rises further upwards along passages formed between the channel surface and the layer of fuel. Secondary air openings are provided on the upper part of the channel surface so that secondary air can be led up from behind the channel surface and through the channel surface onto its front side.
