Abstract (en)

[origin: EP0994321A2] The inner peripheries of the passages through the lamellae for the water pipes contain radial slots (22) that divide the periphery into edge segments (24) clamping tight against the pipes. Combustion gases from the burning fuel pass through gaps in between the lamellae to heat water flowing through the pipes.
