電蒸汽鍋爐蒸汽主要溶解硅酸，因此高壓鍋爐蒸汽污染的原因，除了帶水外，還由于溶解了某些鹽類的緣故。

1、由于電蒸汽鍋爐http://www.scsuntao.cn/爐水的含鹽量較給水含鹽量要大得多，蒸汽帶水就會使蒸汽含鹽量增加。這是中、低壓鍋爐蒸汽污染的主要原因。
Because salinity electric steam boiler feedwater salinity of the water is much greater than the vapor with water vapor will cause increased salinity. That is, the low-pressure steam boiler major cause of pollution.

2、隨著鍋爐壓力的提高，電蒸汽鍋爐http://www.scsuntao.cn/蒸汽的各種性質逐漸接近爐水，因此電蒸汽鍋爐的蒸汽有溶解某些鹽類的性能使爐水中的某些鹽類轉移到蒸汽中去，從而影響蒸汽品質。
With the improvement of the boiler pressure, the various properties of electric steam boiler steam boiler water gradually approaching, so the steam electric steam boilers dissolution performance of certain salts of certain salts transferred to the boiler water to steam, which affects steam quality.
