净化2吨蒸汽锅炉产生的蒸汽有哪些
Purify 2 tons steam boiler produce steam
2吨蒸汽锅炉产生蒸汽后会由锅炉的锅筒排出,而锅炉排出的蒸汽中总是含有一些杂质的,有些杂质以液态状态存在,有些杂质可溶解于蒸汽中,也可能有少量气体杂质混在蒸汽中,这些杂质主要是钠盐、硅盐、二氧化碳和氨等。
When the meeting after steam boiler to produce steam from the boiler drum, and the steam boiler exhaust always contains some impurities, some impurities exist in liquid form, some impurities can be dissolved in steam, there may be a small amount of gas impurities mixed in steam, these impurities are mainly sodium salt, silicon, carbon dioxide and ammonia, etc.
含有杂质的蒸汽通过过热器时,可能有部分杂质沉积在管内壁上,形成盐垢,使壁温度升高,加速钢材的蠕变,严重的甚至产生裂纹而爆破。
Containing impurities by steam superheater, there may be some impurities deposition in the pipe wall and the formation of salt deposit, make the wall temperature, accelerate steel creep, serious and even crack and burst.
剩余的杂质则随蒸汽进入锅炉的汽轮机。蒸汽在汽轮机中膨胀作功,随着蒸汽压力的降低,杂质被析出并沉积在汽轮机的通流部分,致使叶表面粗糙、线型改变和蒸汽通流截面减小,导致汽轮出力和效率降低。
The remaining impurities follow the steam into the turbine of the boiler. In steam turbine expansion work, with the loss of the steam pressure, the impurities were precipitation and deposition in the throughflow section of the steam turbine, the leaf surface is rough, linear change and steam flow cross-section decreases, and results in the decrease of turbine output and efficiency.
另外沉积在主汽门上的盐分将使阀门开启困难,关闭不严。对于制药及食品等工业,生产用汽与产品是直接接触的,如蒸汽携带的杂质超过规定值,将影响产品质量及工艺条件。

Also, the salt deposited on the main steam door will cause the valve to open and shut down. For pharmaceutical and food industries, the production of steam is direct contact with the product, the impurities such as steam carried over specified value, will affect the product quality and process conditions.
