        【蓄熱球產品介紹】:

         

         

         

             蓄熱球又稱球狀蓄熱體,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。

         

         

         

        【蓄熱球的特性】:

         

         

         

             1 、比表面積可達到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,有效的沖破了蓄熱體表面的附面層,又因球徑小,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要求。

         

             3 、蓄熱體可利用20~30次/h的換向,高溫煙氣流經蓄熱體床層后內便可將煙氣降至130℃左右排放。

         

             4 、高溫煤氣和空氣流經蓄熱體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 、因蓄熱體體積十分小巧,加之小球床的流通能力強,即使積灰后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 、陶瓷小球的更換、清洗非常方便,并可重復使用。

         

         

         

        【蓄熱球的應用領域】:

         

         

         

             蓄熱球適用于氣體及非氣體燃料工業爐的蓄熱球燃燒系統選用,特別適用于鋼鐵行業蓄熱式加熱爐、蓄熱式鋼包烘烤器、空分行業空氣分離設備蓄熱器、有色金屬行業蓄熱式熔煉爐,也可用在大型鍛造廠蓄熱式臺車爐、蓄熱式電鍋爐、蓄熱式焚化爐等行業做蓄熱載體。

         

         

         

             蓄熱球通過對煤氣(高爐、轉爐)和空氣雙預熱(油類、高熱值煤氣等則采取助燃空氣單蓄熱方式),可使蓄熱式加熱爐達到排煙量減少20-50%,排煙溫度降至小于150度,產量提高 15-20%,鋼坯加熱時間縮短50%,氧化燒損降低30-50%的環保節能效果。

        【 refractory ball product introduction 】 :

         

         

         

        Refractory ball is industrial alumina and refractory kaolin as the main raw material, through scientific formula, forming and high temperature forging burn, it has the following features:

         

        1, high mechanical strength, long use period;

         

        2, good chemical stability, does not react with the material;

         

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

         

         

         

        Fire ball is divided into common refractory ball and high aluminum refractory, refractory ball particularly applicable to chemical fertilizer plant transformation of high and low temperature transformation furnace, furnace, hydrogenation converter, desulphurizing tank and a chamber in the furnace, the scattered gas and liquid, and support, cover and protect the catalyst. High aluminum refractory ball steel mill industry transformation stove and heating equipment.

         

         

         

        【 regenerative ball product introduction 】 :

         

         

         

        Regenerative ball is also called the ball regenerator, has the linear shrinkage rate is low, the high temperature and high refractoriness under load, corrosion resistance, high strength, heat quantity storage, good thermal shock resistance, good performance, and other significant characteristics of small thermal expansion coefficient of thermal conductivity, is a good refractory material.

         

         

         

        【Features regenerative ball】:

         

         

         

        1, the specific surface area of 240 m2 / m3.

         

        2, many balls will be split into small airflow flows, airflow was outdated in the regenerator, the formation of strong turbulence, effective broke through the accumulation of heat on the surface of the body surface boundary layer, and because the ball diameter is small, small transmission radius, small heat resistance, high density, good thermal conductivity, which can realize regenerative burner frequent and rapid directional control requirements.

         

        3, regenerator can use 20 ~ 30 times/h of the reversing, high temperature flue gas flowing through the regenerator in bed after its flue gas emissions have fallen to about 130 ℃.

         

        4, high temperature gas and air flows through the regenerator in the same path can be preheated to only about 100 ℃ lower than the flue gas temperature, temperature efficiency is as high as above 90%.

         

        5, because of the heat storage volume is very small, combined with the ball the flow capacity of the bed is strong, even after heavy resistance increase does not affect the heat change index.

         

        6, regenerative ball has the characteristics of strong oxidation resistance and slag resistance.

         

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

         

         

         

        【The application field of regenerative ball 】 :

         

         

         

        Regenerative ball is suitable for the gas and the gas fuel industrial furnace of regenerative combustion system is chosen, especially for regenerative heating furnace of steel industry, the regenerative ladle baking equipment, air separation equipment of air separation industry regenerator regenerative furnace, non-ferrous metal industry, also used in large forging plant regenerative trolley furnace, regenerative electric boilers, the regenerative incinerator industries do regenerative heat carrier.

         

         

         

        Regenerative ball of 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%, the oxidation burning loss reduce 30-50% of the environmental protection and energy saving effect
