The biomass boiler Biowarmer was designed in Sweden on the basis of many years of experience, with focus on high thermal and operating comfort, and with particular attention to protection of natural environment. The boiler is designed in such a way that the parts being in contact with ue gas are also in contact with the water jacket of the boiler.
The boiler is of a three-pass type with heat exchange occurring on the surface of hipped convection ducts or, in the case of 200-250 and 300-350 kW models, vertical combustion tubes.
On the front side the boiler has a door to the combustion chamber, a hand hole for cleaning of convection ducts and, in 25-200 kW, with ash box doors. The doors exposed to high temperatures are equipped with re protectors. For sealing of doors a mineral bre stung is used.
