Chemical descaling process:
Recirculating Closed Loop Cleaning
Recirculation cleaning utilizes two existing parallel ash piping lines to form a loop, creating a circulating system with the cleaning pump station. A solution of a certain acidity concentration is added, which circulates and cleans within the ash water pipes. As the acid washing reaches a certain level, 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 while the system is shut down, and it is complex and costly.

Preliminary Cleaning
No two gray pipes should form a loop during cleaning; only single gray pipe open circuit cleaning is allowed. The method involves connecting one end of the gray pipe to the cleaning device, continuously preparing a certain concentration of cleaning solution in the blending tank, and injecting it into the gray pipe continuously or intermittently. This process requires adding cleaning equipment during shutdown, which increases costs.

Continuous cleaning without shutdown
This process involves continuously injecting a certain amount of acidic solution while the ash pipeline is operating normally without interruption. Simultaneously, a specific quantity of ash pipeline cleaning inhibitor and pipeline cleaning descaler is added for operation. The cleaning is conducted with an open circuit. The primary function of the cleaning aids is to facilitate the reaction between the acidic solution and the ash deposits at a certain concentration and flow rate, while also enhancing their solubility in water, reducing air blockage, and ensuring the quality of ash pipeline cleaning.
The procedure is as follows: Before cleaning, first 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 descaling agent and pipeline cleaning agent by considering the sludge water flow and acidity. During the cleaning process, 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 process can be deemed complete.
2. High-pressure water cleaning machinery
High-pressure water jetting is used for cleaning, offering benefits such as high efficiency, low cost, non-damaging to workpieces, non-polluting the environment, easy operation, and safety.
Advantages of high-pressure water technology include:
(1) Excellent Cleaning Quality: The high-pressure water jet cleaning of pipe and heat exchanger bores can completely remove scale and blockages inside, revealing the metal substrate. With immense energy and moving at supersonic speeds, the high-pressure water jet is fully capable of destroying hard scale and blockages without causing any damage to the metal.
Since the pressure of high-pressure water is less than the compressive strength grade of metal, high-pressure cleaning will not damage the base being cleaned.

(2) Fast Cleaning Speed: Due to the combined abrasive actions of water jet flushing, chisel, shearing, and grinding, scaling can be quickly broken and removed, making the cleaning speed several to tens of times faster than traditional chemical methods, sandblasting and shot peening techniques, simple mechanical, and manual methods.
Additionally, parts cleaned with high-pressure water jetting do not require secondary cleaning; however, after chemical cleaning, the surface must be rinsed with clean water.

(3) No Environmental Pollution: As 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 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, 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.
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.

(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, about 2 to 5 times that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it severely impairs heat transfer efficiency and affects the boiler's performance; it can also easily damage metal materials due to localized overheating, potentially leading to pipe explosion accidents; it accelerates galvanic corrosion, causing pipeline lime scale corrosion, and speeds up the deterioration of the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
