Chemical descaling process:
Recirculating Closed Circuit Cleaning
Recirculating cleaning utilizes two original parallel ash piping lines to form a loop, creating a recirculation system with the cleaning pump station. A certain concentration of acidic solution is added, which circulates through the ash water pipes for cleaning. As the acid washing decreases to a certain level, the acidic 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 during shutdown and is complex and costly.

Open Channel Cleaning
No two ash pipes should form a loop during cleaning; only a single ash pipe should be used for open-circuit cleaning. The method involves connecting one end of the ash pipe to the cleaning unit, continuously preparing a specific concentration of cleaning solution in the liquid mixing tank, and then continuously or intermittently injecting it into the ash pipe. This process requires additional cleaning equipment during shutdown, which increases costs.
Continuous cleaning without shutdown
The process involves continuously injecting a certain amount of acidic solution while the ash pipe is operating normally without interruption, simultaneously adding a certain quantity of ash-pipe running cleaning inhibitor and pipeline cleaning descaler for open-loop cleaning. The primary function of the cleaning aids is to promote the reaction between the acidic solution and ash deposits at a specific concentration and flow rate, while also increasing solubility in water and reducing the occurrence of gas blockages, ensuring the quality of ash pipe cleaning.
The procedure is: Prior to cleaning, estimate the required acid amount based on the total scale in the pipeline. Then, calculate the acid addition rate and the flow rate of the ash conveying pipeline by considering the gray water flow rate and acidity. During the cleaning process, collect and test the acidity at the sampling point at the front end of the ash pipeline every 30 minutes, and strictly control the acidity by adjusting the acid flow rate. In the latter stage of cleaning, test the pH value at the end of the ash pipeline every 15 minutes. The cleaning can be deemed complete when the pH value reaches a certain level and remains constant for 30 minutes.

2. High-pressure water jet cleaning machinery
High-pressure water jet cleaning offers advantages such as high efficiency, low cost, non-damaging to workpieces, environmental protection, ease of operation, and safety.
The high-pressure water technology boasts the following advantages.
(1) Excellent Cleaning Quality: The high-pressure water jet cleaning for pipes and heat exchanger bores can thoroughly remove all scale and blockages inside, revealing the metal surface. With its immense energy and ultra-sonic speed, the high-pressure water jet is fully capable of destroying hard scale and blockages without causing any damage to the metal.
Due to the pressure of high-pressure water being less than the compressive strength grade of metal, high-pressure cleaning will not damage the surface being cleaned.

(2) Fast Cleaning Speed: Due to the combined effects of jet washing, wedging, shearing, and grinding, scale can be quickly broken and removed, making the cleaning process several to ten times faster than traditional chemical methods, sandblasting, simple mechanical, and manual methods.
Components cleaned with high-pressure water jetting do not require secondary cleaning; however, after chemical cleaning, the surface chemical agents must be rinsed off with clear water.

(3) No Environmental Pollution: Since high-pressure water jet cleaning uses pure water as the medium, it does not generate large amounts of dust like sandblasting, shot blasting, or simple mechanical cleaning, which can pollute the atmosphere and harm health. It also does not produce large volumes of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet cleaning with pure water as the medium is odorless, tasteless, and non-toxic. After atomization, it can also reduce the dust concentration in the work area, lowering atmospheric dust from 80mg/m³ with other methods to below the national safety standards, thus causing no pollution.

3. Pipe Scale: (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; mixed scale is usually a mixture of the above three types of scales.

(2) Categorized by physical properties, there are two types: scale that is firmly adhered to the pot shell and tube walls, and sediment that is loosely textured and easily detached.
Lime scale primarily forms due to the salts of calcium and magnesium in the boiler feed water, which precipitate and adhere to the metal surface upon heating. Lime scale has a very low thermal conductivity, approximately 2 to 5 times that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it significantly worsens heat transfer efficiency and affects the boiler's performance; it can easily cause metal materials to burn due to localized overheating, potentially leading to pipe explosion accidents; it also accelerates galvanic corrosion, causing pipeline lime scale corrosion and speeding up the damage to the heating surface. Once lime scale forms, it should be promptly removed using either mechanical or chemical methods.
