Product Description

Mullite cordierite

Regenerative high temperature air combustion (HTAC) is a new combustion technology with great energy saving and environmental protection. The regenerator is a key component of regenerative burners. It is widely used in steel, machinery, building materials, petrochemical, and colored. In various furnaces, hot blast furnaces, heat treatment furnaces, cracking furnaces, roasters, melting furnaces, soaking furnaces, oil and gas boilers, etc. in the metal smelting industry, the technology is to make two regenerators through the reversing device. Alternate endothermic heat release, maximally recover the heat of the flue gas, and then heat the combustion air and gas to above 1000 °C, even low-calorie inferior fuel (such as blast furnace gas) can achieve stable ignition and efficient combustion, saving fuel 40 to 70%. The output is increased by more than 15%, the oxidized burning loss of the billet is reduced by more than 40%, the NOx emission is less than 100ppm, and the flue gas discharge temperature is lower than 160 °C, which greatly reduces the global greenhouse effect. If most industrial furnaces and kiln in the country adopt HTAC technology, its economic and social benefits are immeasurable, which will greatly alleviate the shortage of energy and effectively improve the living environment of human beings.
The regenerators are mainly composed of honeycomb ceramics, heat storage balls and heat storage tubes. The specific surface area of the honeycomb ceramic is more than 5 times that of the small ball, the heat transfer capacity is 4 to 5 times larger, and the airflow resistance is only 1/3 of the small ball, and the heat penetration depth is small. Therefore, honeycomb ceramics are more conducive to low-oxygen combustion than heat storage balls, so that the furnace temperature is uniform, the heat transfer rate is fast, and the steel can be quickly tapped, which greatly reduces the oxidation burn and the formation of NOx gas, and
significantly improves the environmental protection and energy saving effect. The volume of the regenerator with honeycomb ceramics is greatly reduced, and a sufficient amount of burners can be arranged to meet the heat load requirements. The direct airflow passage of the honeycomb ceramic is more difficult to block than the labyrinth passage of the small ball, and the self-cleaning property is good, and is more suitable for the uncleanness of burning in China.Corundum/mullite, cordierite/mullite composite phase honeycomb ceramic regenerator has remarkable advantages such as high temperature resistance, acid and alkali corrosion resistance, good thermal shock resistance, high strength, large heat storage capacity and good thermal conductivity. And the service life is greatly improved.

Honeycomb ceramic regenerator regenerative high-temperature combustion technology is a new concept of combustion technology that combines the recovery of flue gas waste heat with efficient combustion and reduction of NOx emissions to achieve extreme energy savings and limit NOx emissions. The dual purpose of quantity.
The technical features are:
(1) Using the regenerative flue gas waste heat recovery device, alternately switching the flue gas and air/gas to make it flow through the regenerator, which can recover the physical heat of the high-temperature flue gas to the maximum extent and save energy (general energy saving 10 %~70%), improve the thermal efficiency of thermal equipment, while reducing CO2 emissions (10% to 70%).
(2) Through the organization of lean oxygen combustion, the flame combustion area is expanded, and the flame boundary is extended to the furnace boundary, so that the temperature distribution in the furnace is uniform, and the NOx emission in the flue gas can be reduced by more than 40%.
(3) The average temperature in the furnace increases, which enhances the heat transfer in the furnace, resulting in the same size of thermal equipment, the output can be increased by more than 20%, reducing the cost of the equipment. (4) Low calorific value fuels can obtain higher furnace temperatures by means of high temperature preheated air or high temperature preheated gas, which expands the application range of low calorific value fuels.
The regenerative honeycomb ceramic, which is also a high-temperature combustion regenerator, is the key and core component of the regenerative high-temperature combustion technology (HTAC technology). It has been widely used in metallurgical machinery industry for various push-type heating furnaces, step-type heating furnaces, heat treatment furnaces, forging furnaces, melting furnaces, ladle/tune roasters, soaking furnaces, radiant tube burners, and hoods. Furnace, blast furnace hot blast stove; various ceramic kiln in the building materials industry, various glass kiln; various tubular heating furnaces, cracking furnaces and other industrial furnaces in the petrochemical industry.
