影响蒸汽锅炉品质的因素有哪些?

燃气蒸汽采用两回程的结构设计,使燃料得到了充分燃烧,热效率高。此外,锅炉在运行过程中的烟管内插有扰流片,使得排烟速度减缓,增加了换热量,为用户降低了大量的使用费用,那么影响蒸汽锅炉品质的因素有哪些呢?
 1、锅水浓度
在锅炉内沸腾的水中有很多气泡,随着锅水浓度的增加,气泡的厚度也不断加厚。锅筒的有效空间则减小,气泡破裂时所溅起的细小水滴就会很容易被向上流动的蒸汽带出,从而使蒸汽品质恶化,严重时会产生汽水共腾现象,并带出大量的锅水。
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、蒸汽锅炉负荷
如果蒸汽锅炉负荷增大,蒸汽在锅筒中的上升速度就会增加,便有足够的能量把水面上高度分散的小水滴带出,使蒸汽品质恶化,甚至出现汽水共腾的严重后果。
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、蒸汽锅炉水位
蒸汽锅炉水位过高,锅筒的蒸汽空间便会缩小,相应的单位体积空间通过的蒸汽量也就增大,蒸汽流速增大,加之水滴的自由分离空间缩小,会使水滴随蒸汽带出,也会使蒸汽品质恶化。
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、蒸汽锅炉压力
当蒸汽锅炉压力突降时,相同质量的蒸汽体积便会增大,单位空间体积所通过的蒸汽体积也就增加。这样,细小的水滴也容易被带出,而影响蒸汽品质。
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.
