Occupations | Operates battery of electrical precipitators to collect metallic dust particles from fumes of smelting ore: Observes ammeters and voltmeters and moves panel controls to regulate flow of electric current to precipitators according to type of ore being smelted, or according to amount of draft, moisture content of dust, and color of stack emission. Switches off electric current. Replaces broken wire in precipitators, using pliers. May turn valves to spray acid and water into chambers to oxidize dust particles. May pull levers to actuate airhammers that knock dust from electrodes. (references) |
| Tends equipment, such as scrubbing towers and centrifugal pumps, that recover powder from spray-tower exhaust gas and prevent air pollution: Starts fan to draw air and accumulated dust from spray tower into scrubbing tower. Starts steam pump to wet powder, causing it to flow down baffle plates to bottom of tower. Opens valve to permit recovered powder to flow into storage tank for reuse. Pumps recovered powder from storage tank to crutcher machine for reprocessing. Records spray-tower exhaust temperatures and gas pressures on chart. (references) | |
