Abstract: A recuperator for furnaces includes a set of tubes, which are installed in a secondary chamber (1) which is located behind a main combustion chamber of the furnace and through which hot fumes can pass from the main combustion chamber towards an outlet. The task of the tubes is to recuperate thermal energy from the fumes by bringing a combustion gas to pass through the tubes on its way to burners in the main combustion chamber. The different tubes of the tube set are designed as individual units (8) each one of which is removably inserted in the secondary chamber (1) through holes in the walls (4) thereof. In the mounted condition each tube has a closed portion projecting into the secondary chamber as well as a portion projecting from the outside of the walls of the secondary chamber, the latter portion having inlets and outlets for cold and preheated combustion gas respectively.
