顶央大型锻造厂蓄热式台车炉 蓄热式电锅炉专用蓄热体蓄热球

【蓄热球产品介绍】

      上海顶央蓄热球又称球状蓄热体，具有重烧线收缩率低、高温荷重软化温度高、耐腐蚀、强度高、蓄放热量大、热震稳定性好、导热性能好、热膨胀系数小等显著特点，是优良的耐火材料。

【蓄热球主要理化指标】

【蓄热球的特性】

      1、比表面积可达到240m2/m3。

      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。

      3、蓄热体可利用20~30次/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。

      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低100℃左右，温度效率高达90%以上。

      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。

      6、蓄热小球具有抗氧化、抗渣性强的特点。

      7、陶瓷小球的更换、清洗非常方便，并可重复使用。

【蓄热球的应用领域】

     蓄热球适用于气体及非气体燃料工业炉的蓄热球燃烧系统选用，特别适用于钢铁行业蓄热式加热炉、蓄热式钢包烘烤器、空分行业空气分离设备蓄热器、有色金属行业蓄热式熔炼炉，也可用在大型锻造厂蓄热式台车炉、蓄热式电锅炉、蓄热式焚化炉等行业做蓄热载体。

     蓄热球通过对煤气（高炉、转炉）和空气双预热（油类、高热值煤气等则采取助燃空气单蓄热方式），可使蓄热式加热炉达到排烟量减少20-50%，排烟温度降至小于150度，产量提高 15-20%，钢坯加热时间缩短50%，氧化烧损降低30-50%的环保节能效果。

the top of the shanghai central regenerative ball is also called the ball regenerator, with reheat shrinkage rate is low, high load softening temperature, corrosion resistance, high strength, large heat storage, heat shock stability, good thermal conductivity, low coefficient of thermal expansion characteristics, excellent refractory material.
regenerative ball for regenerative combustion system of gas and the gas fuel industrial furnace use, especially suitable for the steel industry, regenerative furnace, regenerative ladle baking device, air separation industry of air separation equipment in regenerator, regenerative melting furnace of non-ferrous metals industry, can also be used in large forging factory of regenerative furnace, heat storage trolley the electric boiler, regenerative incinerators and other industries do heat carrier.
regenerative ball through the gas (blast furnace) and air preheating (oil, gas and other high calorific value by combustion air single regenerative mode), can be reached to reduce the amount of exhaust 20-50% regenerative heating furnace, flue gas temperature is reduced to less than 150 degrees, the yield increased 15-20%, billet heating time is reduced by 50% and decrease the oxidation burning loss of environmental protection the energy saving effect of 30-50%.
