Title: Multichamber baking furnace - with independent control of hot recirculating gas heating each chamber
Inventor: MAUERMANN PAUL
IPC: F27D19/00
Filed: 1976-12-29
Abstract: Heating gas flow is controlled according to the temp. of a baking furnace which has >=2 baking chambers and recirculating gas flow. The temp. in each chamber is measured and used to adjust dampers or shutter valves so the gas flow to one chamber can be adjusted independently of the gas flow to the other chamber. The dampers are linked together so a min. hot gas circulation is maintained by a gas generator. In one pref. furnace design, four baking chambers are driven as two pairs sepd. by an additional gas channel which can be at least partly closed by dampers and is thermally insulated from the adjacent hot gas supply ducts; this gas channel is pref. divided into two parallel zones, each with a damper. Efficient hot gas flow, ensuring proper temp. control is achieved.
