Endogas Generators
The Almor Wild Barfield Endothermic Gas Generator is based on the well proven Wild Barfield design and is used for the production of a high quality protective gas. Endothermic gas is produced by passing a sub stoichiometric mixture of a hydrocarbon (natural gas, propane etc.) and air through a heated retort, containing a nickel impregnated catalyst.
Design Features
- Output 15m³/hr to 180m³/hr
- Modular construction for up rating to higher capacity
- Electrically or Gas heated
- Multi-tube catalyst retorts for optimum ‘cracking’ (EN120 – EN180)
- Better than 5:1 automatic turn down
- Natural convection air cooling (no water or electric)
- Fully automatic operation
- PLC control with HMI for control and datalogging
- Range of gas quality control devices (dewpoint, CO2)
- Conforms to BS EN 746:3
Generated carrier gas gives the best controllability, reproducibility and high quality end product, compared with alternative methods of controlled atmosphere production (i.e. nitrogen/methanol, ‘in furnace’ generation) and can be used in a wide variety of heat treatment processes including:-
- Gas carburising (+ hydrocarbon)
- Gas carbonitriding (+ hydrocarbon + ammonia)
- Neutral hardening (+ hydrocarbon)
- Gas nitrocarburising (+ ammonia)
