燃氣蒸汽采用兩回程的結(jié)構(gòu)設(shè)計，使燃料得到了充分燃燒，熱效率高。此外，鍋爐在運行過程中的煙管內(nèi)插有擾流片，使得排煙速度減緩，增加了換熱量，為用戶降低了大量的使用費用，那么影響蒸汽鍋爐品質(zhì)的因素有哪些呢？
1、鍋水濃度
在鍋爐內(nèi)沸騰的水中有很多氣泡，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 pot of water with increasing concentration, the thickness of the bubble has also been thickened. Drum of available space decreases, when the bubbles burst the tiny water droplets splashing upward mobility will be very easy to be out of steam, so that the steam quality deterioration, and in severe produce priming phenomenon, and bring out a lot of pot of water.
2、蒸汽鍋爐負荷
如果蒸汽鍋爐負荷增大，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，甚至出現(xiàn)汽水共騰的嚴重后果。
If the steam boiler load increases, the rising steam drum speed will increase, there will be enough energy to put on the surface of highly dispersed droplets out of the steam quality deterioration, or even the serious consequences of priming.
3、蒸汽鍋爐水位
蒸汽鍋爐水位過高，鍋筒的蒸汽空間便會縮小，相應(yīng)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。
Steam boiler water level is too high, the vapor space of the drum will be reduced, the amount of steam corresponding unit volume of space will increase by a steam flow rate increases, coupled with the free drop separation space narrowing, with the steam will drop out, also cause deterioration of the quality of steam.
4、蒸汽鍋爐壓力
當蒸汽鍋爐壓力突降時，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 the steam boiler pressure dump, the same volume will increase the quality of steam, the steam volume unit volume of space through which it increased. Thus, the small droplets can easily be taken out, and the impact of steam quality.
