Importance of improving the quality of steam produced by steam boilers

For users and friends who need to use steam boilers, boiler thermal efficiency and steam quality directly affect production volume and production costs. Choosing a high-quality and efficient steam boiler can fundamentally reduce operating costs and improve benefits for enterprises. So how to effectively improve the quality of steam produced by the steam boiler? Let the technical engineers of Zhengzhou Fangkuai boiler manufacturer answer for you free of charge.

For steam boilers, steam quality refers to the degree of cleanliness of the steam, which is usually expressed by the total amount of impurities contained in the unit mass of steam; the steam contains various salts, alkalis and oxides and other impurities, and the main part is salt. In the same way, too much impurities in the steam will cause problems such as the surface of the superheater, the flow part of the steam turbine and the salt deposit in the steam pipe.

From the above analysis, we can see that in order to improve the steam quality, the salt content of the boiler water must be strictly controlled. At the same time, attention should be paid to the control of the dissolved salt in the steam and the saturated steam with water to obtain the clean steam required for the operation of the boiler. In order to reduce saturated steam with water, good steam-water separation conditions should be established and a perfect steam-water separation device should be adopted. In order to reduce the dissolved salt in the steam, the alkalinity of the boiler water can be appropriately controlled and a steam cleaning device can be used; in order to reduce the salt content of the boiler water, methods can be adopted to improve the quality of the feed water, perform boiler blowdown, and use segmented steam.
