【蓄热球的特性】：

1、比表面积可达到240m2/m3、�/span>

2、众多小球将气流分割成很小流股，气流在蓄热体中流过时，形成强烈的紊流，有效的冲破了蓄热体表面的附面层，又因球径小，传导半径小、热阻小、密度高、导热性好，故可实现蓄热式烧嘴频繁且快速换向要求、�/span>

3、蓄热体可利�?0~30�?h的换向，高温烟气流经蓄热体床层内，便可将烟气降至130℃左右排放、�/span>

4、高温煤气和空气流经蓄热体在相同路径内即可预热到仅比烟气温度�?00℃左右，温度效率高达90%以上、�/span>

5、因蓄热体体积十分小巧，加之小球床的流通能力强，即使积灰后阻力增加也不影响热换指标、�/span>

【The heat accumulating ballproducts【�

Heat storage ball is a ball shaped heat storage body, with heavy firing line of low shrinkage, high temperature and high refractoriness under load, corrosion resistance, high strength, large heat storage, put good thermal shock resistance,good thermal conductivity, small coefficient of thermal expansion is the significant features, excellent refractory.

【features regenerative ball【�

Refractory ball with industrial alumina and refractory kaolin as the main raw material, scientific formula, forming and high temperature calcined made, it has the following characteristics:

1, high mechanical strength, long use period;

2, good chemical stability, do not react chemically with the material;

3, high temperature resistant performance is good, the highest heat resistanttemperature can reach 1900 DEG C.

【Characteristics heat storage ball【�

1, the specific surface area can reach 240m2/m3.

2, many small balls of the airflow is split into a small stream, flow in the regeneratorflow, the formation of strong turbulence, effectively broke through the boundary layer heat storage body surface, and because the ball size, transmission radius of small, small thermal resistance, high density, good thermal conductivity, so it canrealize the regenerative burning the mouth is frequent and fast reversingrequirements.

3, regenerator can be used 20~30 times /h reversing, high temperature flue gasthrough the regenerator bed, can be reduced to about 130 DEG C emissions fromflue gas.

4, the high temperature coal gas and the air flowing through the heat storage body can be in the same path preheating to only 100 DEG C lower than the temperature of flue gas, temperature efficiency can reach above 90%.

5, because the heat accumulator volume is small, and the pellet bed flow ability,even if the ash after does not affect the heat transfer resistance increase index.

The characteristics of 6, thermal storage ball has antioxidant, high slag resistance.

7, ceramic ball replacement, cleaning is very convenient, and can be repeatedly used.

【The application field of regenerative ball 【�

Regenerative ball is suitable for the combustion system of the regenerative ball gasand non fuel gas industrial furnace used in steel industry, especially suitable for theregenerative heating furnace, regenerative ladle baking device, air separation industry of air separation equipment in regenerator, regenerative furnace of non-ferrous metals industry, also used in large type forging factory regenerative car bottom furnace, heat storage electric boiler, regenerative thermal oxidizer and other industries do heat carrier.

Regenerative ball through the gas (blast furnace) and air double preheating (oil,high calorific value gas is taken combustion air single regenerative way), can reachexhaust to reduce the amount of 20-50% regenerative heating furnace, flue gas temperature is reduced to less than 150 degrees, the yield increased 15-20%, billetheating time is shortened by 50%, decrease the oxidation burning loss ofenvironmental protection energy saving effect of 30-50%.
