Hydrogen Technology Expo North America
Hydrogen Gas Safety System
)
This system is suitable for use with either tube furnaces using a suitable work tube package or chamber furnaces using an A105 retort up to a maximum internal volume of 50 litres.
It is supplied with its own control cabinet, off gas burner and flexible pipes with fittings to connect directly to a gas atmosphere work tube package or chamber A105 retort.
The system automatically purges the work tube or chamber with nitrogen, ensures hydrogen is only introduced to the furnace above a safety temperature of 750 °C, and provides an end purge of nitrogen. A nitrogen purge also occurs in the event of unplanned shutdowns.
Two adjustable flow meters provide the facility for hydrogen and nitrogen flows to be blended to suit the process. A monitored electrically heated gas ignitor ensures the hydrogen is fully consumed.
Standard features:
- Over-pressure protection for the work tube or retort
- Excess flow (rupture) protection
- Purge timer
- Independent safety purge
- Supply gas monitoring
- Furnace temperature monitoring
- Electric ignitor
