Abstract (en)

Heating system with radiant strips comprising a burner (5) housed in a containment structure (3) and provided with a combustion chamber (6) and with means (8) for supplying a fuel mixture and a ventilator (9), housed in the containment structure (3), provided with a fan (10) inserted in a recirculation duct (4) and operating in a suction fashion to force the carrier fluid (F) which traverses the radiant strips (2). The burner (5) is of premix type and comprises a conveniently cylindrical combustion head (12) provided with a metal mesh (13) on which the combustion occurs, and is extended into the combustion chamber (6) for at least the section (7') in which this traverses the recirculation duct (4). The supply means (8) of the burner (5) comprise a modulating blower (14) which suctions an adjustable flow, and an electropneumatic controlled valve (15), which is connected to a source of supply gas, and to the modulating blower (14) to which it is susceptible of sending a gas flow as a function of the air suctioned by the modulating blower (15), which are mixed together in the modulating blower (15) and injected by the latter in the combustion head (12) in order to obtain a flame on the cylindrical mesh (13) thereof.
