Honeycomb Ceramic Regenerator Product introduction and performance
Honeycomb ceramic is a porous industrial ceramic. It has large specific surface area, small resistance, uniform fluid distribution and high separation efficiency. It is widely used in chemical, metallurgy, gas, food, environmental protection and other industries. The material is mainly divided into cordierite, mullite, and alumina ceramic.
Regenerative high-temperature air combustion is a new combustion technology with great energy saving and environmental protection. Honeycomb ceramic regenerator is a key component of regenerative burners, widely used in steel, machinery, building materials, chemicals, petrochemicals, coatings. In various industries such as non-ferrous metal smelting, such as heating furnaces, hot blast stoves, heat treatment furnaces, cracking furnaces, roasters, melting furnaces, soaking furnaces, oil and gas boilers, etc. The technology makes the two regenerators alternately absorb heat and release heat through the reversing device, maximally recovers the heat of the flue gas, and then heats the combustion air and gas in the furnace to above 1000 ° C, even if the low calorific value of the inferior fuel can Achieve stable ignition and high-efficiency combustion, saving fuel by 25%-30%, increasing production by more than 15%, slab oxidation loss by more than 40%, NOx emission less than 100ppm emission of flue gas temperature below 150 °C, greatly reducing the earth The greenhouse effect of the atmosphere. If most industrial furnaces in the country adopt HTAC technology, their economic and social benefits are immeasurable, which will greatly alleviate the shortage of energy and greatly improve the living environment of human beings.
The technology of honeycomb ceramic regenerator is to use the reversing device to make two regenerative types alternately absorb and release heat, recover the heat of the flue gas to the maximum limit, and then heat the combustion-supporting air and gas in the furnace to above 1000'C, even if Inferior combustion with low calorific value can also achieve stable ignition and high-efficiency combustion, which can save fuel up to 40-70C. The output is increased by more than 15'C, the oxidation loss of steel billet is reduced by more than 40%, the NO2 emission is less than 100pm, and the exhaust gas temperature is low. At 150C, the greenhouse effect of the earth's atmosphere is greatly reduced. If most industrial furnaces and kilns in the country adopt HTAC technology, its economic and social benefits will be immeasurable, which will greatly alleviate the situation of energy shortage and improve the living environment of human beings. Since it was put on the market, the effect is good, and it is favored by the steel smelting industry.
