Chemical cleaning descaling 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 certain concentration of acidic solution is added, which circulates through the ash water pipes for cleaning. As the acid washing reduces 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 while the system is shut down, and it is complex and costly.

Pilot Cleaning
During cleaning, no two ash pipes should form a loop; only a single ash pipe can 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 dosing tank, and injecting it into the ash pipe continuously or intermittently. This process requires adding cleaning equipment during shutdown, which increases costs.

Non-stop machine cleaning
This process involves continuously injecting a certain amount of acidic solution while operating, without interrupting the normal ash transportation through the ash pipe. Simultaneously, a specific amount of ash pipe operation cleaning inhibitor and pipeline descaling agent are added for open-circuit cleaning. The primary function of the cleaning aids is to promote the reaction between the acidic solution and ash deposits at a certain concentration and flow rate, while also increasing solubility in water and reducing the occurrence of airlock, ensuring the quality of ash pipe 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 sludge pipeline by considering 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 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, non-polluting to the environment, easy operation, and safety.
High-pressure water technology boasts the following advantages.
(1) Excellent Cleaning Quality: The high-pressure water jet cleaning of pipeline 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.
High-pressure water cleaning will not damage the base material being cleaned, as the pressure is less than the compressive strength grade of the metal.

(2) Fast Cleaning Speed: Due to the combined action of water jet washing, cleaving, shearing, and grinding, scaling can be quickly broken and removed, several to ten times faster than traditional chemical methods, sandblasting and shot blasting techniques, 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 washed off with clean 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 quantities of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet cleaning using pure water is odorless, tasteless, and non-toxic. After atomization, the ejected jet can also reduce the dust concentration in the work area, lowering atmospheric dust levels from 80mg/m³ using other methods to below the national safety standards. Therefore, it does not cause any pollution.

3. Pipe Scale
(1) Categorized by chemical composition, they include carbonate scale, sulfate scale, silicate scale, and mixed scale. The primary 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 often a mixture of the three types mentioned above.

(2) Classified by physical properties, there are two types: scale that firmly adheres to the pot shell and tube wall, and sediment that is loosely textured and easy to dislodge.
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, 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 also lead to the metal being damaged by local overheating, potentially causing a pipe burst; it accelerates galvanic corrosion, leading to pipeline lime scale corrosion and speeding up the deterioration of the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
