Holes in the two devices
Thread Content
What conditions must be met for the manholes of the two devices to be opened?
1. After the deslagging is complete, close the raw material plug valve (sliding valve), turn off the feed pre-heating steam and atomization steam, reduce the amount of stripping steam used, open the vent valve at the top of the settler, and install a blind flange on the oil-gas line. 2. Close all steam valves in the two-unit system, open the drain valve, open the regeneration and standby plug valves (sliding valves), and open the manholes of the reactor and regenerator; after the interior has cooled down, conduct an inspection.
