Honeycomb ceramics
Honeycomb ceramic regenerator is a regenerative high-temperature combustion technology (HTAC technology) the key and core components. Regenerative high temperature combustion technology (HTAC technology) is a new concept of combustion technology, which the flue gas waste heat recovery and efficient combustion and reduce NOx emissions from organically integrate technologies to achieve energy efficiency and limit the limit to reduce NOx emissions from volume of a dual purpose. Honeycomb ceramic regenerator has been widely used in metallurgical machinery industry a variety of Pusher-type furnace, reheating furnace, heat treatment furnace, forging furnace, melting furnace, ladle / tundish toasters, soaking furnace, radiant tube burners, hood-type furnace, blast furnace hot blast stove.
