A need exists to expand the use of conventional boilers for various types of fuels. The present invention constitutes a new solution for a pillarlike auxiliary device (6 and 12) designed to be connected in front of a conventional boiler (1) and comprising a lower part (6) in the form of a hearth with grate (19) for solid fuels and an upper part (12) constituting a store for the solid fuel to be burned, said fuel being supplied to the lower part (6) by means of gravity. The grate (19) of the auxiliary device (6 and 12) is of predetermined size. The connecting part (17) has predetermined throttling. Combustion air is suitably supplied by means of a fan (22) in a predetermined quantity. |
