Abstract

The present invention concerns a boiler (1) comprising a combustion chamber (2) for burning fuel, where means for supplying combustion air are provided in the combustion chamber, where the combustion air is preferably supplied via apertures (5) in the bottom of the combustion chamber under the fuel, which is provided on the air supply means. The invention furthermore concerns an air duct (3) for such a boiler. In such a boiler (1) there is additionally at least one air duct in the combustion chamber for supplying combustion air (secondary air) to the combustion, where the at least one air duct is arranged for supplying combustion air at least one level above the bottom of the combustion chamber. By such an air duct it is possible to supply the combustion with an excess of combustion air, whereby a cleaner and better combustion takes place. In an easy and very simple way it thus becomes possible to achieve an optimal combustion in boilers where such combustion traditionally is not so easy to attain.
