1、在鍋爐內(nèi)沸騰的水中有很多氣泡，當氣泡上升脫出水位瞬間破裂時，會分解出很多細小而分散的小水滴。當鍋水濃度低和鍋爐水位、負荷、壓力正常穩(wěn)定時，這些小水滴并不容易被蒸汽大量帶走。因為水滴本身有一定的重量，當它們?yōu)R出水面升到一定高度時，會蕩回到水中。當鍋水不斷蒸發(fā)，濃縮，鍋水含鹽濃度逐漸增加。鍋水的表面張力也不斷增大，在鍋水沸騰的表面便會產(chǎn)生大量的泡沫層。隨著鍋水濃度的增加，氣泡的厚度也不斷加厚。鍋筒的有效空間則減小，氣泡破裂時所濺起的細小水滴就會很容易被向上流動的蒸汽帶出，從而使蒸汽品質(zhì)惡化，嚴重時會產(chǎn)生汽水共騰現(xiàn)象，并帶出大量的鍋水。
Boiling water in the boiler has a lot of bubbles, the bubbles rise emerge when water instantly rupture, will break a lot of small, dispersed droplets. When the low water concentration and pot boiler water level, load, pressure is normal and stable, these droplets are not likely to be taken away a lot of steam. Because droplets itself has a certain weight, when they spill the water rose to a certain height, it will swing back to the water. When the pot of water constantly evaporation, condensation, pot containing water salinity increased. Pot surface tension of water is also increasing in the boiling pot of water will produce a large amount of surface foam layer. With increasing concentration of boiler water, the thickness of the bubble also been thickened. Drum of the available space is reduced, when the bubbles burst the tiny droplets splashed upward mobility will be very easy to be out of steam, so that the steam quality deterioration, severe Priming phenomenon will produce and bring out a lot of pot of water.
　　
2、電蒸汽鍋爐http://www.scsuntao.cn/負荷增大，即鍋爐內(nèi)單位蒸汽空間每小時通過每小時通過的蒸汽量增加，蒸汽在鍋筒中的上升速度就會增加，便有足夠的能量把水面上高度分散的小水滴帶出，使蒸汽品質(zhì)惡化，特別是負荷波動或超負荷運行時，即使鍋水含鹽濃度不大，也會出現(xiàn)汽水共騰的嚴重后果。
Electric steam boiler load increases, the vapor space per unit increased by the amount of steam per hour per hour through the boiler, the steam rising in the steam drum speed will increase, there will be enough energy to highly dispersed on the water droplets out the steam quality deterioration, particularly load fluctuation or overload operation, even when the pot of water containing salt is not, serious consequences Priming will appear.
　　
3、電蒸汽鍋爐水位過高，鍋筒的蒸汽空間便會縮小，相應的單位體積空間通過的蒸汽量也就增大，蒸汽流速增大，加之水滴的自由分離空間縮小，會使水滴隨蒸汽帶出，也會使蒸汽品質(zhì)惡化，水位波動也會造成蒸汽瞬間帶水。
Steam boiler water level is too high, the vapor space of the drum will be reduced, the amount of steam corresponding unit volume will increase space by the steam flow rate increases, coupled with the free water droplets isolated space narrowing, will make the water droplets with the steam out, also make steam quality deterioration, water level fluctuations will cause steam instantly with water.
　　
4、電蒸汽鍋爐http://www.scsuntao.cn/壓力突降時，相同質(zhì)量的蒸汽體積便會增大，單位空間體積所通過的蒸汽體積也就增加。這樣，細小的水滴也容易被帶出，而影響蒸汽品質(zhì)。
When electric steam boiler pressure dips, the same volume will increase the quality of the steam, the steam volume unit volume of space through which it increased. Thus, the small droplets can easily be taken out, and affect the quality of steam.
