The boiler (1) has a combustion chamber (3) arranged within a reservoir (2). The granules are poured into the combustion chamber through a vertical feed pipe (5). The amount of pellets flows in a combustion crucible (6) is adjusted when the pellets are obstructed in the pipe. A height adjustable cup (7) is supplied with oxidizer i.e. air, through a supply tube (8) and/or a cooling tube (9). The feeding pipe is inserted into the cooling tube, in which the secondary air is circulated, where the feeding pipe and the cooling tube are surrounded by a refractory thermal protection unit (10). |
