蓄熱球特點:
本廠生產的高效蓄熱小球,比表面積可達到240m2/m3。
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,又由于球徑很小,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。
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。
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。
蓄熱小球具有抗氧化、抗渣性強的特點。
陶瓷小球的更換、清洗非常方便,并可重復使用。

Regenerative ball:
Regenerative ball is also called the ball regenerator, ball regenerator has good thermal shock stability, large storage quantity of heat, high strength, easy to clean, reusable, etc. Suitable for gas and the gas fuel industrial furnace of regenerative combustion system is chosen.
Regenerative ball physical and chemical indicators:

Suitable temperature (℃) 1450, 1550, 1650, 1750 or less
Regenerative ball features:
This company produces the high efficient regenerative ball, specific surface area of 240 m2 / m3.
Many balls will be split into small airflow flows, flow in regenerator have been out of date, the formation of strong turbulence, effective broke through the accumulation of heat on the surface of the body surface boundary layer, and as the ball diameter is very small, small transmission radius, small heat resistance, high density, good thermal conductivity, which can realize regenerative burner frequent and rapid directional control requirements.
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 ℃.
High temperature gas and air flows through the regenerator in the same path can preheat separately to only about 100 ℃ lower than the flue gas temperature, temperature efficiency is as high as above 90%.
Because of heat storage volume is very small, and circulation ability of pellet bed, even after heavy resistance increase does not affect the heat change index.
Regenerative ball has the characteristics of strong oxidation resistance and slag resistance.
Ceramic ball replacement, cleaning is very convenient, and can be reused.
Regenerative ball specification: 16 mm Φ Φ 18 mm Φ 20 mm Φ 25 mm
Regenerative ball material: high aluminum zirconium, just the quality of the jade, just the quality of the jade.
Packing: 25 kg/bag, double woven bag
