A laboratory gas safety system is required for safe operation when using hydrogen gas in Carbolite tube furnaces or metallic chamber retorts. Two different sytems are available, one for hydrogen use from 750 °C to Tmax and one for hydrogen use from room temperature to Tmax.
Hydrogen Gas Safety System 1 750 °C to Maximum Temperature
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.
