Infrared ceramic plaque/ plate/ board is mainly used in gas-infrared burners, infrared gas stoves, infrared heaters, gas water heaters and so on. Our company develops and produces Infrared ceramic plaque/ plate/ board with the corrugation surface. It increases the specific surface area through transforming the simple plane surface into intersectant corrugated solid surface. Also, it can promote the combustion supporting function and achieve the goal of energy conserving and environment protection.
