蓄热球特点:

本厂生产的高效蓄热小球，比表面积可达到240m2/m3。

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，又由于球径很小，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的要求。

蓄热体可利用20~30次/h的换向，高温烟气流经蓄热体床层后内便可将烟气降至130℃左右排放。

高温煤气和空气流经蓄热体在相同路径内即可分别预热到仅比烟气温度低100℃左右，温度效率高达90%以上。

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。

蓄热小球具有抗氧化、抗渣性强的特点。

陶瓷小球的更换、清洗非常方便，并可重复使用。

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:

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Many balls will be split into small airflow flows, flow in regenerator have been out of date, the formation of strong turbulence, effective broke through the accumulation of heat on the surface of the body surface boundary layer, and as the ball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
