    Regenerative ball

    The company's yu neng heat storage ball, specific surface area can reach 240m2/m3.Many small ball gas into a small flow unit, flow in the heat storage body obsolete, the formation of strong turbulence, effectively broke through the heat storage body surface boundary layer, and because of the ball diameter is small, small conduction radius, small thermal resistance, high density, good thermal conductivity, it can achieve the requirements of regenerative burner frequent and rapid reversing.The heat storage body can be used for 20~30 times /h of commutation. After the high-temperature flue gas flows through the bed of the heat storage body, the flue gas can be discharged to about 130℃.High temperature gas and air flow through the regenerator in the same path can be preheated to only 100℃ lower than the flue gas temperature, the temperature efficiency is up to more than 90%.Due to the volume of the heat storage body and the strong circulation capacity of the pellet bed, the increase of the resistance after ash accumulation does not affect the heat exchange index.

    Product introduction

    Corundum mullite is an excellent refractory material with low shrinkage rate of reheating line, high softening temperature under high temperature load, corrosion resistance, high strength, large heat storage and discharge, good thermal shock stability, good thermal conductivity and small thermal expansion coefficient.Based on gas (blast furnace, converter) and the air double preheating (oil, high calorific value gas combustion air is taken, such as single heat storage mode), can make the regenerative heating furnace smoke less 20-50%, exhaust smoke temperature dropped to less than 150 degrees, yields by 15-20%, billet heating time shortened by 50%, oxidation burning loss reduce 30-50% of the environmental protection and energy saving effect.

    Product advantage

    1) the * heat storage sphere produced by our company has a specific surface area of 240m2/m3.

    2) many small balls divide the air flow into very small flow unit, the air flow in the heat storage body, the formation of strong turbulence, effectively broke through the heat storage body surface boundary layer, and because of the small ball diameter, conduction radius, small thermal resistance, high density, good thermal conductivity, so can achieve the regenerative burner frequent and fast reversing requirements.

    3) the heat storage body can use 20~30 times /h commutation, and the flue gas at high temperature can be discharged to about 130℃ after flowing through the bed of the heat storage body.

    4) the high-temperature gas and air can be preheated to about 100℃ lower than the flue gas temperature in the same path through the regenerator, and the temperature efficiency is up to over 90%.

    5) due to the volume of heat storage body and the strong circulation capacity of the pellet bed, even the increase of resistance after ash accumulation does not affect the heat exchange index.

    6) heat storage pellets have the characteristics of strong slag resistance.

    7) ceramic ball replacement, cleaning is very convenient, and can be reused.
