Abstract
The invention concerns equipment and a method for enhancing the combustion event and heat transfer in a heating boiler. According to the invention, the space above the major combustion zone in the combustion space of the heating boiler is equipped with sound sources, which are used to generate an acoustic field to enhance the combustion event and to achieve more complete combustion.
Claims17
Equipment for enhancing the combustion event and heat transfer in a heating boiler, said equipment comprising sound sources (S) in a space above the major combustion zone in a combustion space (11) of the heating boiler (10), which sound sources (S) generate an acoustic field in order to enhance the combustion event and a more complete combustion, characterised in that the sound sources (S) are placed in such a way that the acoustic pressure patterns generated by the sound sources (S) meet at angles of 20-90° sideways and/or vertically and that the sound sources (S) are fitted into the heating boiler (10) in such a way that the generated acoustic field is rotating.
Method for enhancing the combustion event and heat transfer in a heating boiler, in which method an acoustic field is generated with sound sources (S) in a space above the major combustion zone in a combustion space (11) of the heating boiler (10), characterised in that a rotating acoustic field is generated by sound sources (S), which are located on various sides and/or at different elevations of the heating boiler (10) in such a way that the acoustic pressure patterns generated by the sound sources (S) meet at angles 20-90° sideways and/or vertically.
