Emisshield is a nano-ceramic coating that provides the highest infrared heating capabilities. Our coatings improve oven energy efficiency from 15%-25% and create a better product in both new and current ovens.
The coating was applied to the walls, crown and burner blocks in the 50 meter soak zone only. After several months of production, an energy balance and audit showed that natural gas savings were in the 8-10% range, the greater savings occurring at the higher push rates.
The afterburner chamber is 80 feet long, six feet tall and 42 inches across. By reradiating energy back into the afterburner chamber, the amount of fuel needed to keep the afterburner at 1400°F was reduced.
This was a relatively small commercial heat treating furnace used to heat high alloy castings to a maximum temperature of 2230°F. This furnace was highly monitored and complete baseline performance data were available. At the time the coating was applied, all refractory substrates had seen extensive service.
Emisshield was applied to the refractory and carbon steel tubes within a water wall gas boiler. Benefits include the ability to lower excess air to the boiler and improve boiler efficiency between 4-5%.
