Abstract (en)

[origin: WO9821526A1] The invention relates to a method of accomplishing, in a heating boiler (100) for heating houses and intended for the combustion of fossil fuels and/or renewable fuels, an optimized combustion and an effectual decrease of the temperature of the combustion gases generated when burning the fuel in a burner (2) introduced into a combustion room (1) of the heating boiler, whereby the combustion room (1) is manufactured from a highly alloyed temperature and corrosion resistant material, the combustion gases through a flue duct (6) are brought from the combustion room to a condenser (7) in which the combustion gases are forced to condense, i.e. they are cooled to a temperature below the dew point, the condenser (7) and the flue duct (6) are likewise manufactured from a highly alloyed, temperature and corrosion resistant material and the cooled combustion gases from the condenser are directly, i.e. without the use of a chimney, brought to the atmosphere by using a fan (9) which is governed by at least one sensor (10) to ensure an excess of air in the combustion process. The invention also relates to a heating boiler.
