Radiation recuperators

These recuperators transfer heat (thermal energy)between primary and secondary flows by radiation.

Jacketed  radiation recuperators offer a reduction of 40% or more in fuel consumption. Their compact design facilitates its installation in the gas exhaust chimney.

They are made of two concentric cylinders in which the secondary fluid circulates through a circular crown, either parallel to the recuperator axis or helically, in counter or in parallel flows. Suitable for working pressures up to 2000mm WG (water gauge).

For higher working pressures, tube basket type recuperators offer better performance, greater resistance and a more homogeneous air distribution. They are designed replacing the inner shell with a tube basket with an annular layout, through which the air circulates, so the heat transfer continues to be carried out by radiation.
