Product Introduction
YLX corundum-mullite regenerative heat storage balls feature low shrinkage on heavy firing, high softening temperature under load, corrosion resistance, high strength, large heat storage and release capacity, good thermal shock stability, good thermal conductivity, and low thermal expansion coefficient, making them excellent refractory materials. By using dual preheating of gas (blast furnace, converter) and air (for oil and high-calorific gas, a single regenerative heat storage method with combustion-supporting air is used), regenerative heating furnaces can reduce flue gas volume by 20-50%, lower flue gas temperature to below 150°C, increase output by 15-20%, shorten billet heating time by 50%, and reduce oxidation loss by 30-50%, achieving environmental protection and energy saving. Alumina content is 65-99%.
Product Features
1) The high-efficiency regenerative heat storage balls produced by our company have a specific surface area of up to 240m2/m3.
2) Numerous small balls divide the airflow into very small streams, creating strong turbulence as the airflow passes through the heat storage body, effectively breaking the boundary layer on the surface of the heat storage body. Due to the small ball diameter, small conduction radius, low thermal resistance, high density, and good thermal conductivity, frequent and rapid switching of regenerative burners can be achieved.
3) The heat storage body can utilize 20~30 reversals per hour; after high-temperature flue gas passes through the heat storage bed, the flue gas temperature can be reduced to about 130°C before discharge.
4) High-temperature gas and air flowing through the heat storage body in the same path can be preheated to only about 100°C lower than the flue gas temperature, achieving a temperature efficiency of over 90%.
5) Because the heat storage body is very compact and the small ball bed has strong flow capacity, even if resistance increases due to dust accumulation, it does not affect heat exchange performance.
6) The regenerative heat storage balls have strong oxidation resistance and slag resistance.
7) Ceramic balls are very easy to replace and clean, and can be reused.
Application Fields
YLX regenerative heat storage balls are suitable for regenerative heat storage ball combustion systems in gas and non-gas fuel industrial furnaces. They are especially suitable for steel industry reheating furnaces, regenerative ladle heaters, air separation equipment regenerators in the air separation industry, regenerative melting furnaces in the non-ferrous metal industry, and can also be used as regenerative carriers in large forging plant regenerative walking beam furnaces, regenerative electric boilers, regenerative incinerators, and other industries. YLX regenerative heat storage balls are divided into solid balls and concave-convex perforated balls.
