Honeycomb ceramic regenerators are currently widely used in energy-saving technology of industrial thermal equipment to increase efficiency, reduce energy consumption, increase output and improve quality of industrial thermal equipment. It is an important and effective means to solve energy and environmental problems. The cross-sectional holes of honeycomb ceramic regenerators mainly have two hole structures: square and regular hexagonal, and the holes are straight channel structures parallel to each other. This structure greatly reduces the resistance of the pores to flow through and greatly improves the single-hole volume heat transfer efficiency of the heat storage body.

       Regenerative high-temperature air combustion (abbreviation: HTAC) is a new combustion technology with huge energy-saving and environmentally friendly double-layer effects. This technology uses a reversing device to alternately absorb and release heat in two regenerators, maximizing recovery The heat of the flue gas then heats the combustion air and gas in the furnace to above 1000°C. Even low-quality fuel with low thermal quality can achieve stable ignition and efficient combustion. It can save fuel by 40-70% and increase output by more than 15%. NOx emissions are less than 100ppm, and the exhaust gas temperature is less than 150°C, which greatly reduces the greenhouse effect of the atmosphere.

       Honeycomb ceramic regenerator is a key component of regenerative burner. It is a new type of industrial ceramic product made of ceramic raw materials that have been treated with special processes, extruded from a special mold, and sintered at high temperatures.

       There are two main types of heat storage bodies: honeycomb ceramics and heat storage balls. The specific surface area of honeycomb ceramics is more than 5 times that of the sphere, the heat transfer capacity is 4 to 5 times greater, the air flow resistance is only 1/3 of the sphere, and the heat penetration depth is small. Therefore, the honeycomb ceramic regenerator is more conducive to low-oxygen combustion than regenerative balls, making the furnace temperature uniform, rapid heat transfer, greatly reducing oxidation burning loss and the generation of NOx gas, and significantly improving environmental protection and energy saving effects.

       In terms of material classification, the honeycomb ceramic regenerators developed by our company include: cordierite, dense cordierite, mullite, zirconium mullite, mullite corundum, chromium corundum, alumina, stoneware (acid-resistant porcelain ), spinel, silicon carbide, etc. It has significant features such as high temperature resistance, corrosion resistance, good thermal shock stability, high strength, large heat storage and release, and good thermal conductivity.
