- Product Description
-
The Honeycomb ceramic heat accumulator is made of high-performance ceramic materials such as corundum, mullite or silicon carbide, and is structured in a honeycomb-like pattern with numerous parallel flow channels. Its core working principle is to utilize the large specific surface area of the ceramic body to quickly absorb and store the thermal energy when the hot exhaust gas passes through, and then release the stored thermal energy when the cold air passes through, completing efficient heat exchange. This product has significant characteristics such as large heat storage capacity, high heat exchange efficiency, good thermal shock stability, and resistance to high-temperature corrosion. It is a key component for achieving energy conservation and cost reduction in industrial furnaces and exhaust gas treatment systems.
