Honeycomb Ceramic Regenerator

Product Detail



    Honeycomb ceramic carrier, also known as high temperature combustion regenerator, is the key and core component of high temperature combustion technology (HTAC). It has been widely used in various pusher type heating furnaces, walking type heating furnaces, heat treatment furnaces, forging furnaces, melting furnaces, ladle / tundish roasters, soaking pits, radiant tube burners, bell type furnaces, blast furnace hot blast furnaces in the metallurgical machinery industry; various ceramic furnaces, various glass furnaces in the building materials industry; various tube type heating furnaces, cracking furnaces and other industrial furnaces in the petrochemical industry.


    Regenerative high temperature combustion technology is a new concept of combustion technology. It combines the recovery of flue gas waste heat with efficient combustion and NOx emission reduction technology, so as to achieve the dual purpose of limiting energy saving and NOx emission reduction.

    Dense cordierite honeycomb ceramic regenerator is widely used in HTAC for gas exchange and heat storage. It has the following advantages:


    The regenerative flue gas waste heat recovery device is used to alternately switch the flue gas and air / gas to flow through the regenerator, which can maximize the recovery of physical heat of high-temperature flue gas, greatly save energy (generally 10% - 70%), improve the thermal efficiency of thermal equipment, and reduce CO2 emissions (10% - 70%).


    Through the organization of lean oxygen combustion, the flame combustion area is expanded, and the flame boundary is almost extended to the furnace boundary, so that the temperature distribution in the furnace is uniform, and the emission of NOx in the flue gas can be reduced by more than 40%.


    The increase of the average temperature in the furnace strengthens the heat transfer in the furnace, resulting in the increase of the output of thermal equipment with the same size by more than 20% and the reduction of the cost of the equipment.


    Low calorific value fuel can obtain higher furnace temperature by means of high temperature preheating air or high temperature preheating gas, which expands the application range of low calorific value fuel.
