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 certain concentration of acidic solution is added, which circulates through the ash water pipes for cleaning. As the acid washing reaches 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.

Break-in Cleaning
No two gray pipes should form a loop during cleaning; only single-pipe open circuit cleaning is allowed. The method involves connecting one end of the gray pipe to the cleaning device, continuously preparing a specific concentration of cleaning solution in the blending tank, and then continuously or intermittently injecting it into the gray pipe. This process requires additional cleaning equipment during shutdown, resulting in higher costs.
Continuous 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-loop 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 enhancing its solubility in water, reducing the occurrence of air blockages, and ensuring the quality of ash pipe cleaning.
The procedure is as follows: Prior to 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 sludge pipe operation by considering the sludge flow rate and acidity. During cleaning, take a sample at the front of the sludge pipe every 30 minutes to test the acidity, and strictly control it by adjusting the flow rate of acid addition. In the later stages of cleaning, test the pH value at the end of the sludge pipe every 15 minutes. 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 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.
The advantages of high-pressure water technology include:
(1) Excellent cleaning quality - High-pressure water jet cleaning of pipes and the inner holes of heat exchangers can thoroughly remove all scale and obstructions inside, revealing the metal surface. 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 base being cleaned.

(2) Rapid Cleaning Speed - Due to the combined crushing effects of water jet scouring, wedge splitting, shearing, and abrasion, scaling can be quickly broken and removed. This is several to tens of times faster than traditional chemical methods, sandblasting, simple mechanical, and manual cleaning techniques.
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 large amounts of dust like sandblasting, grit-blasting, or simple mechanical cleaning, which can pollute the air and harm health. Nor does it produce a large volume of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet, using pure water, is odorless, tasteless, and non-toxic. After atomization, it 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, thus preventing any pollution.

Pipe Scale
(1) Categorized by chemical composition, they include carbonate scale, sulfate scale, silicate scale, and mixed scale, among others. The primary components of carbonate scale are calcium carbonate and magnesium carbonate; sulfate scale and silicate scale are mainly composed of calcium sulfate and silicate compounds, respectively; mixed scale is often a mixture of the above three types.
(2) Classified by physical properties, there are two types: scale that firmly adheres to the pot shell and pipe walls, 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 precipitating and adhering 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 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.
