Abstract
142,710. Teisen, T. July 16, 1919. Tunnel kilns and furnaces; glass furnaces. - In a furnace such as an annealing kiln or lehr for glassware &c. in which the goods are passed through a tunnel-like chamber, any desired temperature gradient is obtained by means of a number of dampered outlets c spaced along the tunnel and connected to a common flue d which is arranged below the tunnel and has two or more clampered connexions e to the chimney. Hot. waste gases can thus be withdrawn as desired along the tunnel, while cold air entering at the exit end is prevented from causing a too sudden drop of temperature. The heating chamber g is fired from a combined producer b, the hot gas from which is either burnt before entering the chamber g, or, as shown, is burnt in the chamber g itself. The secondary air may be heated by contact with the flue d or in the walls of the pro. ducer. The goods may be exposed to the hot gases or enclosed within a muffle.
