Abbott Furnace Company designed, manufactured and installed a 6,000-SCFH endothermic gas generator at Sintergy Inc. in Reynoldsville, Pa. The generator has an innovative retort design that allows a single retort to produce endo gas at this rate without sacrificing gas quality and maintaining a 6:1 turndown ratio. According to Sintergy, a manufacturer of powder-metal components, it is only seeing ±1°F in dew-point variation from setpoint. Abbott included state-of-the-art controls with an Allen-Bradley PLC, data logging, dew-point and methane sensors, and an updated gas safety system.
The endothermic generator has been used in heat treating for decades. It was first introduced into the heat-treating market to produce consistency for a nonoxidizing, carbon-rich source for a neutral or carburizing atmosphere.
To continue a trend we started in 2017, Industrial Heating will highlight a topic on our website and list the most-popular articles under that topic according to page views.
The father of the endothermic gas generator was a gentleman by the name of Norbert K. Koebel, who was fond of saying to young engineers such as The Doctor, “Treat ‘em right, and they’ll treat you right.” He knew that the endothermic gas generator was the heart of any atmosphere heat-treat operation.
United Process Controls (UPC) delivered an Atmosphere Engineering EndoFlex endothermic-gas generator to Jomarca, a fastener manufacturer in South America. The generator is intended for carburizing operations at the company’s Brazilian plant, which includes 10 large continuous rotary-retort furnaces that process over 2,200 tons of fasteners a month. The high-capacity generator was integrated into the plant’s existing gas-distribution system in the first quarter of 2018 and is supplying endothermic gas to all carburizing furnaces.
In 2017, AFC-Holcroft received a large number of orders for complete UBQA (universal batch quench austemper) lines from companies serving a variety of industries. In addition, sales were strong for AFC-Holcroft’s flagship UBQ (universal batch quench) systems, EZ endothermic gas generators, rotary-hearth furnaces, pusher furnaces and mesh-belt equipment. These orders came from the U.S., Canada and Mexico as well as Australia, Europe and Asia.
Can-Eng Furnaces International Ltd. has been awarded a contract to design and build a 1,500-pounds/hour mesh-belt furnace system for the austenitizing and molten salt quenching of unique components used in the manufacture of drivetrain systems.
