Honeycomb ceramics

Honeycomb ceramic thermal storage materials have significant advantages such as high temperature resistance, corrosion resistance, good thermal shock stability, high strength, large heat storage capacity, and good thermal conductivity, greatly improving energy efficiency and service life. Regenerative high-temperature air combustion is a new combustion technology with significant energy-saving and environmental protection benefits. Honeycomb ceramic thermal storage is a key component of regenerative burners, widely used in various heating furnaces, hot blast furnaces, heat treatment furnaces, cracking furnaces, ovens, melting furnaces, soaking furnaces, oil and gas boilers and other kilns in industries such as steel, machinery, building materials, chemistry, petrochemicals, coatings, and non-ferrous metal smelting. This technology uses a reversing device to alternately absorb and release heat in two heat storage chambers, maximizing the recovery of heat from flue gas. Then, the combustion air and gas in the furnace are heated to above 1000 ℃. Even low-quality fuel with low calorific value can achieve stable ignition and combustion, saving fuel by 25% -30%, increasing production by more than 15%, reducing oxidation and burning loss of steel billets by more than 40%, and the temperature of flue gas emitted with NOx emissions less than 100ppm is lower than 150 ℃, Greatly reducing the greenhouse effect of the Earth's atmosphere. If the majority of industrial kilns in the country adopt HTAC technology, its economic and social benefits are immeasurable, which will alleviate the shortage of energy and greatly improve the living environment of humanity.
