Honeycomb ceramic heat storage body has many remarkable advantages, such as high temperature resistance, corrosion resistance, good thermal shock stability, high strength, large heat storage capacity, good thermal conductivity, etc., and its energy-saving effect and service life are greatly improved. Regenerative high temperature air combustion is a new combustion technology with great energy saving and environmental protection effects. Honeycomb ceramic regenerator is the key component of regenerative burner, which is widely used in various furnaces, such as heating furnaces, hot blast furnaces, heat treatment furnaces, cracking furnaces, roasters, melting furnaces, soaking pits, oil and gas boilers, etc. in steel, machinery, building materials, chemistry, petrochemical, coating, non-ferrous metal smelting and other industries. This technology makes the two regenerators alternately absorb heat and release heat through the reversing device to maximize the heat recovery of flue gas, and then heats the combustion air and gas in the furnace to more than 1000 Even the inferior fuel with low calorific value can achieve stable ignition and efficient combustion, which can save fuel up to 25% - 30%, increase the output by more than 15%, reduce the oxidation burning loss of steel billet by more than 40%, and reduce the flue gas temperature of NOx emission less than 100 ppm to less than 150 The greenhouse effect of the earth's atmosphere has been greatly reduced. If most industrial kilns in the country adopt HTAC technology, its economic and social benefits are immeasurable, which will greatly alleviate the situation of energy shortage and greatly improve the living environment of human beings.
