Abstract (en)

[origin: EP0359306A2] Boiler with heat transfer by convection between a heat source and a profiled heat exchanger (3), characterized in that the surface of the profile applied to the heat exchanger and over which the heat transfer takes place, increases with increasing distance from the heat source. Preferably, the profile applied to the heat exchanger is formed by fins, the surface of which increases the further the fins are remote from the heat source.
