Patent number: 8692161Abstract: An infrared firing furnace includes a case-integrated cooling system to provide high performance cooling as the first step in the cooling process. The cooling system includes a cooling manifold integrated into, and made from, the same case material as the adjacent firing zone. As the cooling system is made from the same material as the rest of the case, it can handle being exposed to higher temperatures. The cooling system is positioned such that the plane of its outlet is at a specific clearance level relative to the product passing underneath. High pressure cooling jets of air are directed downward toward the products as they pass under the cooling manifold in order to quickly bring the temperature of the products down from the much higher firing temperature, and minimize the dwell time of the product at the higher temperature.Type: GrantFiled: July 28, 2011Date of Patent: April 8, 2014Assignee: BTU International, Inc.Inventors: Timothy R Doherty, Derek J Butland
