Chemical descaling process:

Recirculating cleaning utilizes two existing parallel ash pipeline sections to form a loop, creating a recirculation system with the cleaning pump station. A solution of a certain acidity concentration is added, which circulates within the ash water pipeline for cleaning. As the acid washing reduces to a certain level, the solution is continuously replenished with acid. For short-distance single ash water pipelines, if conditions permit, a temporary pipeline can be laid to form a recirculation loop for cleaning. This process must be carried out while the system is shut down, and it is complex and costly.

No two gray pipes can form a loop during cleaning; only a single gray pipe can be used for open-loop cleaning. The method involves connecting one end of the gray pipe to the cleaning device and continuously preparing a certain concentration of cleaning solution in the liquid preparation tank, then injecting it into the gray pipe continuously or intermittently. This process requires the addition of cleaning equipment during shutdown, resulting in higher costs.

The process involves continuously injecting a specific amount of acidic solution while simultaneously introducing a certain quantity of running ash pipe cleaning inhibitor and pipeline descaler. This is done through an open-loop cleaning. The main function of the cleaning aids is to promote the reaction between the acidic solution and the ash deposits at a certain concentration and flow rate, while also increasing its solubility in water, reducing airlock formation, and ensuring the quality of ash pipe cleaning.

High-pressure water jet cleaning offers advantages such as high efficiency, low cost, non-damaging to workpieces, environmental-friendly, easy operation, and safety.
High-pressure water technology boasts the following advantages.

Due to the pressure of high-pressure water being less than the compressive strength grade of metal, high-pressure cleaning will not damage the base material being cleaned.

Parts cleaned with high-pressure water jetting do not require a second cleaning process; however, after chemical cleaning, the surface needs to be washed off with clean water.

(1) Classified by chemical composition, they can be categorized into carbonate scale, sulfate scale, silicate scale, and mixed scale, etc. The main components of carbonate scale are calcium carbonate and magnesium carbonate; the main components of sulfate scale and silicate scale are calcium sulfate and silicate compounds, respectively.

Lime scale primarily forms due to the salts of calcium and magnesium in the boiler feedwater, which precipitate and adhere to the metal surface upon heating. The thermal conductivity of lime scaleCorrosion intensifies, causing scale corrosion in pipelines and accelerating damage to the heated surfaces. Once scale forms, it should be promptly removed using either mechanical or chemical methods.
