ABSTRACT:
The invention relates to a radiant-heating device for heating an industrial furnace using radiated heat. A first burner unit (1) comprises a first burner (2), which heats an air mixture by burning a fuel (6), a first air supplier (60), via which the first burner (2) is supplied with fresh air, and a first elongated radiant-heating pipe (20), which includes a rearward end (20a) connected with the first burner (2) and a forward end (20b) spaced from the rearward end (20a) and in which the hot exhaust gas generated by the first burner (2) flows from the rearward end (20a) to the forward end (20b) of the first radiant-heating pipe (20) and supplies heat energy along this path to the pipe wall of the first radiant-heating pipe (20). A second burner unit (1′) is constructed like the first burner unit (1). A first connection element (50) connects the rearward end (20a) of the first radiant-heating pipe (20) with the forward end (20b′) of the second radiant-heating pipe (20′), so that at least a portion of the exhaust gas generated in the second radiant-heating pipe (20′) is conducted to the first burner (2) and is burned again using the first burner. A second connection element (50′) connects the rearward end (20a′) of the second radiant-heating pipe (20′) with the forward end (20b) of the first radiant-heating pipe (20), so that at least a portion of the exhaust gas generated in the first radiant-heating pipe (20) is conducted to the second burner (2) and is burned again using the second burner.
