The tasks aFurnace Operator (Chemical) is expected to perform include:
• Controllingthe continuous-process furnace andrelated equipment to decompose salt cake,forming hydrogen chloride
• Startingthe salt conveyors or shovelling salt cake into furnace
• Turningthe valves to fill furnace reaction pot withsulphuric acid from supply tank
• Setting the burners, dampers, and venting to fire furnace tospecified temperature and effect liberation ofhydrogen chloride
• Using instrument readings and formulae and setting feed scales and timers forcontinuous operation
• Regulating the feed and temperature controls to maintainproduction in conformity with plantstandards
• Removing scale from furnace walls and agitating salt cake to maintain efficientproduction, using scrapers and rake
• Starting or regulatingthe speed of salt-removal device toprepare furnace for new charge
• Maintaining the log of shift production, gauge readings, andequipment failures
