Natural gas has potential to become a lower-cost energy alternative to electric resistance heating for process temperatures above 1800 F in controlled-atmosphere furnaces. The program is intended to develop advanced features in an indirect gas-fired intergal quench furnace used in the metals heat-treat industry. Engineering design and testing produced an advanced high temperature radiant-tube heating system with greatly increased heat input, operating temperatures up to 2050 F and thermal efficiency over 70%. An advanced hearth was also developed to increase the weight of heat treated work that could be handled in each batch. These major improvements are expected to increase the productivity operation. A total furnace design was completed and released for construction of a prototype gas-fired integral quench furnace. The furnace improvements developed in the program will benefit the operation of all gas-fired furnaces using radiant tubes and operating up to 2050 F.
