75%含量蓄熱球 開孔瓷球
蓄熱球外形呈球狀,具有重燒線收縮率低、高溫荷重軟化溫度高、耐腐蝕、強度高、蓄放熱量大、熱震穩定性好、導熱性能好、熱膨脹系數小等顯著特點,是優良的耐火材料。
眾多蓄熱球將氣流分割成很小流股,氣流在蓄熱體中流過時,形成強烈的紊流,有效的沖破瞭蓄熱體表麵的附麵層,又由於球徑很小,傳導半徑小、熱阻小、密度高、導熱性好,故可實現蓄熱式燒嘴頻繁且快速換向的要求。蓄熱球可利用20~30次/h的換向,高溫煙氣流經蓄熱體床層後內便可將煙氣降至130℃左右排放。高溫煤氣和空氣流經蓄熱體在相同路徑內即可分別預熱到僅比煙氣溫度低100℃左右,溫度效率高達90%以上。
1、蓄熱球比表麵積可達到240m2/m3。
2、眾多小球將氣流分割成很小流股,氣流在蓄熱體中流過時,形成強烈的紊流,有效的沖破瞭蓄熱體表麵的附麵層,又因球徑小,傳導半徑小、熱阻小、密度高、導熱性好,蓄熱球可實現蓄熱式燒嘴頻繁且快速換向要求。
3、蓄熱球可利用20~30次/h的換向,高溫煙氣流經蓄熱體床層內,便可將煙氣降至130℃左右排放。
4、高溫煤氣和空氣流經蓄熱球在相同路徑內即可預熱到僅比煙氣溫度低100℃左右,溫度效率高達90%以上。
5、因蓄熱球體積十分小巧,加之小球床的流通能力強,即使積灰後阻力增加也不影響熱換指標。
6、蓄熱小球具有抗氧化、抗渣性強的特點。
7、蓄熱球的更換、清洗非常方便,並可重復使用。

Heat storage ball shape is spherical, with heavy firing line contraction rate is low and the refractoriness under load of high temperature, corrosion resistance, high strength, storage of heat, good thermal shock resistance, good thermal conductivity, thermal expansion coefficient is small, and other notable features. It is of excellent refractory.
Characteristics of regenerative ball
1, the specific surface area can reach 240m2/m3.
2, many small ball will air flow into a small stream unit, the flow of air flow in the regenerator, the formation of a strong turbulence, effectively broke through the surface of the heat storage body, and because the ball diameter is small, small radius, low thermal resistance, high density, good thermal conductivity, it can realize the heat storage type burning mouth frequently and fast change request.
3, the heat storage body can be used for the /h 20~30, the high temperature gas flow through the heat storage bed, can be reduced to 130 degrees Celsius gas emissions.
4, high temperature gas and air flow through the heat storage in the same path can be preheating to only the flue gas temperature of 100 degrees Celsius, the temperature efficiency of 90% above.
5, because in the storage volume of the heating body is very small, coupled with the flow capacity of the pellet bed strong, even if the ash deposition increase in resistance after does not affect the heat change index.
6, the heat storage ball has the characteristics of anti oxidation, slag resistance.
7, the replacement of ceramic balls, cleaning is very convenient, and can be reused.
Regenerative ball applicable to gas and the gas fuel industrial furnace of regenerative combustion system is used, especially in iron and steel industry regenerative heating furnace, regenerative ladle baking device of the air sub industry of air separation equipment storage device, non-ferrous metals industry regenerative smelting furnace, can also be used in large forging factory regenerative bogie hearth furnace, heat storage type electric boiler, heat storage type incinerator industry as heat storage carrier.
Regenerative ball through for blast furnace, converter gas and air double preheating (oil, high calorific value gas, take combustion air single regenerative way), the regenerative heating furnace to achieve emission reduction of 20-50%, flue gas temperature is reduced to less than 150 degrees, the yield increased by 15-20%, billet heating time shorten 50%, the oxidation loss reduce 30-50% of the effect of environmental protection and energy saving.
