摘要:
The invention concerns an industrial furnace comprising a thermally insulated enclosure and a plurality of burners distributed in a plurality of heating areas, the furnace further comprising recovery means (6) intended to recover heat energy from recovery fumes (F2) originating from a first combustion carried out by the burners. According to the invention, the recovery means (6) comprise a rotary regenerator (7) associated with each heating area (Z1, Z2, Z3), each of the rotary regenerators (7) being suitable for receiving a predefined flow of recovery fumes and a predefined flow of supply air, and for preheating this supply air in order to supply the burners (3) in the associated heating area with a predefined flow of preheated combustion air (9).
