Chemical cleaning descaling process:
Recirculating Closed-loop Cleaning
Recirculating cleaning utilizes two existing parallel ash pipelines to form a loop, creating a circulation system with the cleaning pump station. A solution of a certain acidity concentration is added, which circulates through the ash water pipes for cleaning. As the acid washing decreases to 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 circulation loop for cleaning. This process must be carried out while the system is shut down, and it is complex and costly.

Preliminary 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 mixing tank, and then injecting it into the ash pipe continuously or intermittently. This process requires additional cleaning equipment during shutdown, which increases costs.

Continuous operation cleaning
The process involves continuously injecting a certain amount of acidic solution while the ash pipe is operating normally without interruption, simultaneously adding a specific quantity of ash pipe running cleaning inhibitor and pipeline descaling agent for open-circuit 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 increasing its solubility in water and reducing the formation of gas blockages, ensuring the quality of ash pipe cleaning.
The procedure is as follows: Before cleaning, estimate the required acid quantity based on the total scale in the pipeline. Then, calculate the acid addition rate and the flow rate of the descaling agent and pipeline cleaner based on the sludge flow rate and acidity. During cleaning, take a sample at the front end of the sludge pipe every 30 minutes to test the acidity and strictly control it by adjusting the acid flow rate. In the later stage of cleaning, take a sample at the end of the sludge pipe every 15 minutes to test the pH value. When the pH value reaches a certain level and remains unchanged for 30 minutes, the cleaning can be considered complete.

2. High-pressure water cleaning machinery
High-pressure water jet cleaning is efficient, cost-effective, non-damaging to workpieces, environmentally friendly, easy to operate, and safe.
Advantages of high-pressure water technology include:
(1) Excellent Cleaning Quality: The high-pressure water jet cleaning for pipes and heat exchanger bores can completely remove scale and obstructions inside, revealing the metal substrate. With its immense energy and supersonic speed, the high-pressure water jet is fully capable of destroying hard scale and obstructions without causing any damage to the metal.
Since the pressure of high-pressure water is less than the pressure resistance grade of metal, high-pressure cleaning will not damage the cleaned substrate.
(2) Fast Cleaning Speed: Due to the combined crushing effects of water jet washing, wedge splitting, shearing, and grinding, scale can be quickly broken and removed, making the cleaning speed several to ten times faster than traditional chemical methods, sandblasting, ball-shot peening, simple mechanical, and manual methods.
Components cleaned with high-pressure water jet do not require secondary cleaning; however, after chemical cleaning, the surface chemicals need to 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 a significant amount 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, the喷射 stream 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, they include carbonate scale, sulfate scale, silicate scale, and mixed scale. 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.
(2) Categorically divided by physical properties, there are two types: scale that firmly adheres to the pot and tube walls, and sediment that is loosely textured and easily detached.
Lime scale primarily forms due to the salts like calcium and magnesium in the boiler feed water precipitating and adhering 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 the heat transfer efficiency and affects the boiler's performance; it can easily cause metal materials to burn due to localized overheating, even 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 mechanical or chemical methods.
