In any industrial heating process perhaps the most critical aim is to provide a carefully controlled temperature profile within the kiln or furnace,also can use custom silicon carbide ceramic. Whether the fuel is natural gas, LPG or oil, the location of silicon carbide burner nozzle is a potential hot-spot within the kiln. Burner flames can be long enough to make contact with the product or kiln furniture causing very severe over-heating which is damaging to both. Even when the exposed flame is kept at a safe distance, direct radiant heating can cause localised over-heating of product and subsequent quality problems.
