This program is intended to develop advanced features in an indirect gas-fired integral quench furnace used in the metals heat-treat industry. Engineering design and testing produced an advanced high-temperature radiant-tube heat system with greatly increased heat input, operating temperatures up to 2050/sup 0/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 have increased productivity. A furnace design was completed and a prototype gas-fired integral quench furnace was constructed. This unit was both laboratory and field tested. It is now being used for heat-treating production in a large commercial heat treat shop. The furnace improvements developed in the program will benefit the operation of all gas-fired furnaces using radiant tubes and operating up 2050/sup 0/F. Natural gas has potential to become a lower-cost energy alternative to electrical-resistance heating for process temperatures above 1800/sup 0/F in controlled-atmosphere furnaces.
