I. Problems Existing in Boiler Water Treatment

1, Boiler water treatment was not implemented

      At present, some boilers are often not given due attention because of their relatively small capacity or they are only used in winter. Moreover, the personnel managing small boilers often lack experience in boiler water treatment and fail to implement effective boiler water treatment during the boiler management process, resulting in scaling or corrosion of the boilers. Over time, it has had a serious impact on the management of boilers.

2, The water treatment method for the boiler is inappropriate

      At present, many enterprises and institutions often adopt unscientific methods for the treatment of boiler water in order to save greater expenses. Moreover, the various tools and equipment used in the process of boiler water treatment do not comply with relevant regulations, such as""Three no's"Electronic scale prevention instruments and scale prevention agents, etc. Moreover, if the scale inhibitor is not used properly, it will have the opposite effect on the protection of the boiler, accelerating the scaling and corrosion of the boiler, posing a serious threat to the normal operation of the boiler.

3The boiler water was not given due attentionpHvalue

      For steam-type boilers, the hardness index of feed water is very important. The hardness of boiler water often affects the scaling and corrosion problems in the later stage. If the hardness of the boiler water is relatively high, it will cause scaling due to evaporation, and hot water boilers are relatively more prone to corrosion.

4, Problems with the boiler water treatment equipment

      If the quality of the water produced by the water treatment equipment used in the boiler water treatment process is poor and the water output efficiency is low, it often accelerates the scaling and corrosion of the boiler. The main reason is that the resin was improperly used, causing it to be damaged and eventually oxidized. Or it could be that the inner walls of the iron boiler were not treated in a timely and appropriate manner, resulting in iron poisoning of the resin. Or perhaps the river water was not filtered before being used as boiler water, causing the resin to be clogged with silt and thus unable to function properly.

Ii. Solutions to Boiler Water Treatment Problems

      1For those who have not implemented boiler water treatment, a comprehensive consideration should be given to the boiler, boiler water and local conditions. For boilers with large evaporation capacity and high steam pressure, external chemical treatment should be carried out, and corresponding deaeration instruments must be installed. For cases where natural water contains a large amount of impurities, effective treatment measures such as sedimentation or filtration should be adopted to achieve boiler water treatment in a timely manner.

   2In cases where the water treatment methods for boilers are inappropriate, the treatment approach for boiler water should be readjusted. The application of new technologies must be approved by relevant departments and reported to the local labor department for record before the new technologies can be applied to the designated boilers.

      3Boiler waterPHOnly by adjusting the range can the probability of boiler scaling and corrosion be reduced. General boiler waterPHThe value should remain at10~12During this period, if the hardness of the boiler water is too high, soda ash should be appropriately supplemented to increase itPHValue within an appropriate range;

  4Appropriate measures should be taken for the situation where the boiler water treatment equipment is substandard. For instance, when using resin exchangers, the method of external chemical treatment of the boiler should be adopted. In the case of iron poisoning of the resin, a reasonable analysis should be conducted based on the corresponding situation to identify the cause and develop an appropriate plan for the recovery treatment of the resin. Moreover, regular anti-corrosion and inspection work should be done well.
