The process
Tile, sanitaryware and tableware kilns run on gas with combustion air blowers, a kiln exhaust fan on the preheat zone, and hot air fans that recover cooling zone heat for the dryers. The exhaust carries fluorine and sulphur compounds from the body and glaze.
The gas
Kiln exhaust with light dust and fluorine or sulphur compounds from the body and glaze. Hot, mildly corrosive; stainless steel or coated construction on the wetted parts.
Selection for this process
| Type | Guillotine for isolation, multi louver or butterfly for control, diverter where the gas is switched between two paths |
| Material | SS 310 or SS 316 for gas above 300°C or corrosive |
| Sealing | Seal air arrangement where tight shut-off is needed on hot or dusty gas |
