漂珠的形成机理：燃煤电厂多将煤炭磨成煤粉，喷入发电锅炉的炉膛，让其悬浮燃烧。煤的可燃成分（炭和有机物）大部分燃烧，而粘土质不可燃成分（硅、铝、铁、镁等）在炉膛摄氏1300度的高温下开始熔融，形成石英玻璃和莫来石多孔共生体，其孔内充满气体。当炉温达到摄氏1400度时，熔融体颗粒表面张力会使表面能降到最低值，棱角摆脱表面能而收缩，熔融颗粒会飘浮滚动形成球体。这时，多孔体内的气体如CO、CO 2、N2、H 2等被包裹在球内。当炉温继续升高时，玻璃球体内的气体膨胀，使球体增大，外壳变薄，形成中空球体。当中空球体离开炉膛，急速冷却后，就变成了坚硬外壳的玻璃微珠。这些玻璃微珠，因壁厚及轻重不同，可分为两类。其中一类是薄壁中空球体（壁厚为直径的十分之一），因可漂水上，就称为“漂珠”。另一类是壁厚中空球体（壁厚为直径的三分之一）和实心球体，因较重而沉于水底，故城“沉珠：，含铁量高的称为“磁珠”。漂珠在粉煤灰中含量甚微，一般仅为0.2－0.5％，少数可达1％：沉珠量很大，约为粉煤灰的30－70％。漂珠的产量和质量，跟煤种、煤的细度、锅炉负荷、燃烧状况等因素有关。各电厂之间、一个电厂不同锅炉之间、一个锅炉不同时间，均有极大差别。一般发热量高、含硫量低的烟煤，漂珠量多：无烟煤漂珠少，褐煤漂珠极少甚至无漂珠。炉膛内温度低于摄氏1400度，很少形成漂珠：摄氏1400－1500度，形成漂珠多，摄氏1500度以上，形成的漂珠会爆裂成碎片。因此炉温过高或过低都会影响漂珠的形成。
自己实在不会翻译，需要给外国人看，帮帮忙，专业一点，老外能看懂就行。十分感谢！！

The drift-formation mechanism: coal-fired power plant and more coal will be ground into pulverized coal, power generation injected into the boiler furnace, burning them suspended. Coal combustible elements (carbon and organic) most of combustion, and the clay of non-combustible components (silicon, aluminum, iron, magnesium, etc.) in the furnace at 1,300 degrees of heat began to melt, the formation of quartz glass and mullite porous Symbiont , The hole filled with gas. When the temperature reached 14 degrees Celsius, melt the surface particle surface tension will be reduced to the minimum value, edges and corners from the surface and can be contracted, will melt particles floating in a rolling sphere. At this time, in the porous gas such as CO, CO 2, N2, H 2, and so was wrapped in ball. When the temperature continues to rise, the glass ball in the gas expansion, increasing sphere, shell thinning, a hollow sphere. Among air balls from the furnace, rapid cooling, it becomes a hard she
