Chemical Cleaning Scale Removal Process
Recirculating Closed Loop Cleaning
Recirculating cleaning utilizes two existing parallel ash piping lines to form a loop, creating a recirculation system with the cleaning pump station. A solution of a certain concentration is added, and it circulates within the ash water pipeline for cleaning. Additionally, as the acid washing process reaches a certain point, acid 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 it is complex and costly.
Open-channel cleaning
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 unit, continuously preparing a certain concentration of cleaning solution in the liquid preparation tank, and then injecting it into the gray pipe continuously or intermittently. This process requires adding cleaning equipment while the system is shut down, which increases the cost.

Non-stop cleaning
The process involves continuously injecting a certain amount of acidic solution while operating the ash conveying pipes, simultaneously adding a specific quantity of ash conveying pipe cleaning inhibitor and pipeline descaling agent for open circuit cleaning. The primary function of the cleaning aids is to facilitate the reaction between the acidic solution and ash deposits at a certain concentration and flow rate, while also enhancing its solubility in water and reducing the occurrence of airlock, ensuring the quality of ash pipe cleaning.
The procedure is as follows: 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 for the injection of the corrosion inhibitor and pipeline cleaner stripper based on the sludge water 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 the acidity 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 jet cleaning equipment
High-pressure water jet cleaning offers advantages such as high efficiency, low cost, non-damaging to workpieces, environmental friendliness, ease of operation, and safety.
Advantages of high-pressure water technology include:
(1) Excellent Cleaning Quality: High-pressure water jet cleaning of pipeline and heat exchanger bores can thoroughly remove scale and obstructions inside, revealing the metal substrate. The high-pressure water jet, with its immense energy and supersonic speed, is fully capable of destroying tough scale and obstructions 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) Rapid Cleaning Speed: Due to the combined action of abrasive, wedge splitting, shearing, and grinding from water jetting, scaling can be quickly broken and removed, several to tens of times faster than traditional chemical methods, sandblasting, simple mechanical, and manual cleaning methods.
Additionally, parts cleaned with high-pressure water jetting do not require secondary cleaning; however, after chemical cleaning, the surface chemical agents must be rinsed off with clean water.
(3) No Environmental Pollution: Since high-pressure water jet cleaning uses pure water as the medium, it does not generate a large amount of dust like sandblasting, shot blasting, or simple mechanical cleaning, which can pollute the atmosphere and harm health. It also does not produce a large volume 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) Categorically divided by physical properties, there are two types: a solid scale that firmly adheres to the pot shell and pipe walls, and a loose sediment that is easily detached.
Lime scale primarily forms due to the salts like 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, about 2 to 5 times that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it severely degrades the heat transfer efficiency and affects the boiler's performance; it can also easily cause metal materials to burn due to localized overheating, potentially leading to pipe explosion accidents; it accelerates galvanic corrosion, causing pipeline lime scale corrosion, and speeds up the damage to the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
