摘要

An industrial oven with tunnel for the baking of pizza or similar alimentary products is shown, made up of a bearing structure ( 10 ) in refractory material comprising an inlet mouth ( 40 ) and one of outlet ( 41 ) connected by a passing through tunnel ( 4 ) along which a baking surface ( 5 ) supporting pizza or similar alimentary products slides. Said oven is heated with firewood and it comprises slits ( 22, 24 ) for the passage of primary air for the combustion of the firewood and air for the oxidation of the excess smoke, said primary and secondary air being moved by fans ( 50 ) controlled by a control unit which processes data on the composition of the air detected inside the oven by sensors ( 26 ), a top combustion chamber ( 15 ) housing top furnaces ( 17 ) made up of top grates ( 18 ) supporting combustible firewood and a bottom combustion chamber ( 16 ) housing bottom furnaces ( 30 ) made up of bottom grates ( 31 ) supporting combustible firewood.
