Ceramic Honeycomb Heat Storage Substrate:
High Temperature Air Combustion (HTAC) is new-type combustion technology with great energy-saving and environment protection. This technology is to make two regenerators to absorb heat and send out heat alternatively through the reversal valve, recuperate the heat of the exhaust gas to the maximum extent, then heat the combustion-supporting air and coal gas to over 1000° C, even the inferior fuel of lower calorific power can also catch fire steadily and burns high-efficiently. The heat storage honeycomb ceramic as heat exchange media is the key part of HTAC.
Ceramic Honeycomb heater is widely used in gas radiant heaters and plays the most important part in those applications. The interlaced corrugated surface of the ceramic tile combined with honeycomb design basis provides a superb surface area and working burning surface. We have also adopted the best raw material and new formula to maximize the micro-porosity of the tile. With all these advantages, the oxygen mix completely with the gas, burning without flame, emitting high efficiency far infrared ray and radiant heat, saving up to 40%-50% energy cost. Honeycomb ceramic heat accumulation substrate heat capacity can be achieve at more than J/kgk1000. Use a temperature≥ 1700° C in the heating furnace, roaster, soaking furnace, pyrolysis furnace, fuel can be savings of more than 40%, increase in production for more than 15%. The flue gas temperature below 150° C. So It has got a wide application in many industrial productions.
The corundum/mullite and cordierite/mullite complex thermal storage honeycomb ceramic developed contains characters: Perfect high temperature resistance, anticorrosion, perfect thermal shock stability, high mechanical strength, large thermal storage capacity, advantaging heat conduction property, energy conserving result and service life are improved greatly.
