1、在锅炉内沸腾的水中有很多气泡,当气泡上升脱出水位瞬间破裂时,会分解出很多细小而分散的小水滴。当锅水浓度低和锅炉水位、负荷、压力正常稳定时,这些小水滴并不容易被蒸汽大量带走。因为水滴本身有一定的重量,当它们溅出水面升到一定高度时,会荡回到水中。当锅水不断蒸发,浓缩,锅水含盐浓度逐渐增加。锅水的表面张力也不断增大,在锅水沸腾的表面便会产生大量的泡沫层。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 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、电蒸汽锅炉http://www.jnshengxin.cn/负荷增大,即锅炉内单位蒸汽空间每小时通过每小时通过的蒸汽量增加,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,特别是负荷波动或超负荷运行时,即使锅水含盐浓度不大,也会出现汽水共腾的严重后果。
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、电蒸汽锅炉水位过高,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,水位波动也会造成蒸汽瞬间带水。
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、电蒸汽锅炉http://www.jnshengxin.cn/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 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.
