Surface Combustion Rx Endothermic Gas Generator, 6000 Cfh, Dual Retort, 1.69M Btu/H, 575V

The Surface Combustion RX endothermic gas generator is an industrial atmosphere generator designed to produce a consistent reducing gas for metallurgical heat treatments. This specific unit features a capacity of 6,000 CFH (170 m3/hr), utilizing a dual-retort configuration. The system operates by cracking a mixture of air and natural gas over a nickel-based catalyst within heavy-wall, heat-resistant cast alloy reaction tubes at temperatures approximately 1010°C (1850°F). The resulting RX gas composition is nominally 40% hydrogen, 40% nitrogen, and 20% carbon monoxide, with trace amounts of carbon dioxide and methane. Electrical specifications for this unit include a power requirement of 7.75 kVA at 575 VAC, 3-phase, 60 Hz, with a full load amperage of 9.8 A. The heating system consists of eight main burners and one pilot burner, with a total maximum fuel consumption of 1,689,200 BTU/H. The reaction process requires 1,282,350 BTU/H at 0.25 PSI, while the fuel gas accounts for 406,850 BTU/H at 0.25 PSI. The system includes a positive displacement mixture pump, air or water product gas coolers to freeze reactions, and advanced controls for real-time dew point and carbon potential monitoring. This generator is optimized for processes such as gas carburizing, carbonitriding, neutral hardening, and bright annealing, offering a 6:1 turndown capability to maintain gas chemistry during varying production demands.
