Chemical cleaning descaling process:

Recirculating Closed-loop Cleaning

Recirculating cleaning utilizes two existing parallel ash removal pipelines to form a loop, creating a recirculation system with the cleaning pump station. A certain concentration of acidic solution is added, and it 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 it is complex and costly.

Open Channel Cleaning

No two grey pipes should form a loop during cleaning; only a single grey pipe should be used for open-loop cleaning. The method involves connecting one end of the grey pipe to the cleaning unit, continuously preparing a specific concentration of cleaning solution in the dosing tank, and then injecting it into the grey pipe continuously or intermittently. This process requires additional cleaning equipment to be installed 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. This is an open-circuit cleaning method. 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 occurrence of air blockages, ensuring the quality of ash-pipe cleaning.

The procedure is: Before cleaning, first estimate the required acid amount based on the total scale in the pipeline, then calculate the acid addition rate and ash flow rate according to the gray water flow and acidity. During cleaning, collect samples at the sampling point at the front of the ash pipe every 30 minutes to test the acidity and strictly control it by adjusting the acid flow rate. In the later stage of cleaning, test the pH value at the end of the ash pipe every 15 minutes. 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 machinery
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: The high-pressure water jet cleaning of pipelines and the inner holes of heat exchangers can completely remove scale and obstructions from inside the pipes, revealing the metal substrate. The high-pressure water jet, with its immense energy and supersonic movement, 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 compressive strength grade of metal, high-pressure cleaning will not damage the substrate being cleaned.

(2) Fast Cleaning Speed: Due to the combined actions of jet washing, chisel splitting, shearing, and abrasion, scale can be quickly shattered and removed, several to ten times faster than traditional chemical methods, sandblasting and shot peening, 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 must be rinsed with clean water.

(3) No Environmental Pollution - Since high-pressure water jet cleaning uses clean water as the medium, it does not produce 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 generate a large volume of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet, using clean water as the medium, is odorless, tasteless, and non-toxic. After atomization, the emitted jet 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. Therefore, it does not cause any 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.

(2) Categorized by physical properties, there are two types: scale that is firmly adhered to the pot shell and pipe walls, and sediment that is loosely textured and easy to detach.
Lime scale primarily forms due to the salts like calcium and magnesium present 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 the heat transfer efficiency, affecting 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 mechanical or chemical methods.
