Chemical descaling process:

Recirculation cleaning utilizes two original parallel descaling pipelines to form a loop, which, together with the cleaning pump station, creates a recirculation system. A certain concentration of acidic solution is added and circulated through the ash water pipes for cleaning. As the acid washing reaches a certain level, the acid solution is continuously replenished. 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 is complex and costly.

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

The process involves continuously injecting a certain amount of acidic solution while operating, without interrupting the normal ash transportation through the ash pipes. Simultaneously, a specific quantity of ash pipe running cleaning inhibitor and pipeline descaling agent is added for open-loop cleaning. The primary function of the cleaning aids is to promote the reaction between the acidic solution and the ash scale at a certain concentration and flow rate, while also enhancing its solubility in water, reducing the formation of air blockages, and ensuring the quality of ash pipe cleaning.

High-pressure water jet cleaning offers high efficiency, low costs, non-damaging to workpieces, non-polluting to the environment, ease of operation, and safety benefits.
High-pressure water technology boasts the following advantages.

Since the pressure of high-pressure water is less than the pressure resistance grade of metal, high-pressure cleaning will not damage the base being cleaned.

Additionally, components cleaned with high-pressure water jetting do not require secondary cleaning.

(1) Classified by chemical composition, it can be divided 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 containing calcium and magnesium in the boiler feed water, which precipitate and adhere to the metal surface upon heating. The thermal conductivity of the scaleCorrosion intensifies, leading to scale corrosion in pipelines and accelerates the damage to heated surfaces. Once scale forms, it should be promptly removed using mechanical or chemical methods.
