Abstract

There is described a boiler comprising a firing means, e.g. a feed screw conveyor, for feeding bio-fuel, e.g. wood pellets, from a fuel silo to a combustion retort (2) in the boiler, a furnace chamber (4), a water filled convection section (16) and a flue gas exhaust (10), where the furnace chamber (4) has smooth walls and is surrounded by the convection section (16), i.e. this and the furnace chamber (4) mainly have common walls, and where the flue gas exhaust (10) is disposed under the combustion retort at the bottom of the furnace chamber (4). By means of simple measures, hereby is achieved a boiler with lesser radiation and convection losses and which has an improved combustion technique and a more effective heat transmission to the boiler water, i.e. a greater efficiency.
