Gas Atmospheres Model XL annealing atmosphere generators have been proven in use in many applications where metal heat treating processes require a rich exothermic atmosphere. XL atmosphere generators are designed to produce combustibles ranging from 11% to 22%, from a variety of gaseous hydrocarbon fuels.
Typical atmosphere generator applications include:
- Bright annealing of low carbon steel
- Clean annealing of silicone steels
- Annealing of tin plate
- Brazing of dissimilar metals onto low carbon steels
- Reduction of surface oxides on metals
These Gas Atmospheres annealing atmosphere generators are completely piped, wired and assembled in a packaged unit, providing ease of installation and maintenance.
The standard atmosphere generator design employs a shell and tube heat exchanger to reduce the product gas temperature to approximately 15°F above the available cooling water temperature.
A nozzle-mix burner system is supplied, with ceramic fiber refractory lining. A thermal shock of frequent start-ups and shutdowns will not shorten the life of this lining.
The generator can be producing a full reducing atmosphere in less than 10 minutes. This shortened start-up not only increases production operating time, but also saves utility costs for fuel, power and water.
The Gas Atmospheres unique burner design also provides desired gas analysis without the use of expensive catalyst.
Safety controls are provided for automatic shutdown in the event of utility failure.
Detailed specifications for standard generator models are available on request. In addition to standard units, Gas Atmospheres will design and engineer equipment to suit specific applications.
