Radiant wall for heat exchangers, muffle kilns and similar equipment

Claim 1

A radiant wall, intended in particular for heat exchangers, muffle kilns and similar equipment, comprising: a plurality of rotating bodies arranged together to form a wall for the separation of two environments, said bodies containing means between which an exchange of thermal energy is brought about, said bodies being rotatable about axes lying parallel with the wall itself and comprising a plurality of variable speed rollers revolving side by side in mutual tangential contact, each roller rotating in an opposite direction to that of an adjacent roller, wherein said plurality of rollers comprises: a first plurality of driving rollers disposed to rotate on axes that are parallel and spaced apart at a given regular distance one from the next; a second plurality of driven rollers disposed to rotate on axes that are parallel and spaced apart at a given distance such that the axes of rotation of the driving rollers are located in a plane different from those of the driven rollers and wherein the regular distance spacing apart the driving rollers is less than a radius of each driven roller, such that each driven roller is supported by two adjacent driving rollers, associating therewith by direct contact, and set in rotation by friction.
