Boiler scale removal, why is it labor-intensive? 【Basic Knowledge】

If the corrosiveness is low, is monitoring unnecessary? The concept of boiler chemicals.

■Why was traditional scale removal labor-intensive? Traditional scale removal required the addition of a separate scale remover in addition to the usual boiler chemicals when scale attachment was confirmed. During this process, monitoring had to be conducted to prevent corrosion of the boiler heat transfer surfaces. ■Why was monitoring necessary? Generally, the agents used to dissolve scale not only react with scale components like calcium carbonate but also with the steel of the boiler base material. Therefore, it was necessary to continuously monitor the state of the chemical solution to avoid excessive dissolution of the base material. ■What changes if the chemicals have low corrosiveness? Certain boiler chemicals have very low corrosiveness and can be applied under normal operating conditions without the need for special monitoring. If the risk of corrosion to the base material itself is low, the effort of monitoring to prevent it becomes unnecessary. ■What can be achieved with a single chemical? There are chemicals that can prevent scale attachment, remove attached scale, and also handle high-concentration operations such as silica, all with just one product.
