Abstract (en)
[origin: EP2236953A2] Device for heating air during the duty cycle of a heating boiler fired in particular by solid fuel or biomass, composed of a conduit for supplying air to the furnace and a conduit for outflow the exhaust gas from the heating boiler into the flue, characterised in that the device has the closed exhaust gas conduit (2) which over the length of its connection with the flue (8) is shaped resembling a cosine curve with advantageously vertical exhaust gas conduits (4) adhered to the vertical air conduits (11) which over the length of the air conduit (3) have a shape resembling a sine curve, and on the last vertical conduit (5), where the end section (7) of the exhaust gas conduit (2) is guided to the flue (8), there is a pumping fan (6). The closed exhaust gas conduit (2) in the shape resembling a cosine curve has vertical exhaust gas conduits (4) which decrease in volume in the flue (8) direction, and the air conduit (3) in the shape resembling a sine curve has vertical air conduits (11) which increase in volume in the boiler (1) direction.
