Chemical Cleaning Scale Removal Process
Recirculating Closed Loop Cleaning
Recirculating cleaning utilizes two original parallel ash removal pipelines to form a circuit, creating a recirculation system with the cleaning pump station. A certain concentration of acidic solution is added, which circulates through the ash water pipeline for cleaning. As the acid washing reaches a certain level, the solution is continuously replenished with more acid. For short-distance single ash water pipelines, if conditions permit, a temporary pipeline can be laid to form a recirculation circuit for cleaning. This process must be carried out while the system is shut down, and it is complex and costly.

Open Channel Cleaning
No two ash pipes can form a loop during cleaning; only single-pipe open circuit cleaning is allowed. The method involves connecting one end of the ash pipe to the cleaning unit, continuously preparing a specific concentration of cleaning solution in the blending tank, and then continuously or intermittently injecting it into the ash pipe. This process requires additional cleaning equipment during shutdown, resulting in higher costs.
Continuous cleaning without downtime
The process involves continuously injecting a certain amount of acidic solution while the ash pipe is operating normally and not shut down, simultaneously adding a certain amount of ash-pipe running cleaning inhibitor and pipeline descaling agent, and performing an open-circuit cleaning. The main function of the cleaning aid 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 blockage, 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 of the descaling agent and pipeline cleaning agent by considering the sludge water flow rate and acidity. During cleaning, collect a sample at the front end of the sludge pipe every 30 minutes to test the acidity and strictly control it by adjusting the acid flow rate. In the later stages 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 deemed complete.

2. High-pressure water jet cleaning equipment
High-pressure water jet cleaning offers high efficiency, low costs, non-damaging to workpieces, environmental friendliness, ease of operation, and safety.
High-pressure water technology boasts the following advantages.
(1) Excellent Cleaning Quality - The high-pressure water jet cleaning method effectively removes all scaling and blockages from pipes and the internal cavities of heat exchangers, revealing the metal surface. With its immense energy and supersonic speed, the high-pressure water jet is capable of completely destroying tough scaling 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 crushing effects of water jetting, wedging, shearing, and grinding, scale can be quickly broken and removed, making the cleaning process several to ten times faster than traditional chemical methods, sandblasting, simple mechanical, and manual 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, grit-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.
Pipe Scale
(1) Classified by chemical composition, it can be categorized 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) Categorized by physical properties, there are two types: hard scale that firmly adheres to the pot shell and tube walls, and loose sediment that is easy to detach.
Lime scale primarily forms due to the salts like calcium and magnesium in the boiler feed water that 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 heat transfer surface, it significantly worsens the heat transfer efficiency, affecting the boiler's performance; it also tends to damage metal materials by localized overheating, potentially leading to pipe explosion accidents; and it accelerates galvanic corrosion, causing pipeline lime scale corrosion and speeding up the deterioration of the heat transfer surface. Once lime scale forms, it should be promptly removed using either mechanical or chemical methods.
