Chemical cleaning descaling process:
Recirculating Closed Circuit Cleaning
Recirculating cleaning utilizes two existing parallel ash removal pipelines to form a loop, creating a circulation 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 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 while the system is shut down, and it is complex and costly.

Open road cleaning
During cleaning, it is not allowed for two gray pipes to form a loop; only single-pipe cleaning is permitted. The method involves connecting one end of the gray pipe to the cleaning unit, continuously preparing a certain concentration of cleaning solution in the fluid storage tank, and injecting it into the gray pipe continuously or intermittently. This process requires the addition of cleaning equipment during shutdown, resulting in higher 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-loop cleaning process. 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, reducing the formation of air blockages, and 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 cleaner by considering the sludge water flow rate and acidity. During cleaning, take samples 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 stage 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 can be considered complete.

2. High-pressure water 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 pipe and heat exchanger bores can completely remove scale and blockages inside, revealing the metal substrate. With its immense energy and ultra-sonic speed, 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 tensile strength grade of the metal.
(2) Fast Cleaning Speed: Due to the combined fracturing effects of water jet cleaning, wedge splitting, shearing, and grinding, scale can be quickly broken and removed, making the cleaning speed several to ten times faster than traditional chemical methods, sandblasting, ball peening techniques, simple mechanical, and manual methods.
Components cleaned with high-pressure water jetting do not require secondary cleaning.

(3) No Environmental Pollution: Since high-pressure water jet cleaning uses pure water as the medium, it does not produce a large amount of dust like sandblasting or simple mechanical cleaning, which can pollute the atmosphere and harm health. Nor does it generate 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 levels from 80mg/m³ with other methods to below the national safety standards, thus ensuring no pollution.

Pipe Scale
(1) Categorized by chemical composition, they include carbonate scale, sulfate scale, silicate scale, and mixed scale, among others. 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 often a mixture of the above three types of scales.
(2) Classified by physical properties, there are two types: water scale that is firmly adhered to the pot body and pipe walls, and sediment that is loosely textured and easy to detach.
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. The thermal conductivity of scale is very low, about 2 to 5 times that of ordinary steel. When scale accumulates on the boiler's heat-absorbing surface, it significantly worsens heat transfer efficiency and affects the boiler's performance; it can easily cause metal materials to burn out due to localized overheating, even leading to pipe explosion accidents; it also accelerates galvanic corrosion, causing pipeline scale corrosion and hastening the damage to the heat-absorbing surface. Once scale forms, it should be promptly removed using either mechanical or chemical methods.
