Chemical Cleaning Scale Removal Process
Recirculating Closed-loop Cleaning
Recirculating cleaning utilizes two existing parallel ash pipelines to form a loop, creating a recirculation system with the cleaning pump station. A certain concentration of acidic solution is added, which circulates within 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 while the system is offline, and it is complex and costly.
Open road cleaning
No two ash pipes should form a loop during cleaning; only a single ash pipe should be used for open-circuit cleaning. The method involves connecting one end of the ash pipe to the cleaning unit, continuously preparing a certain concentration of cleaning solution in the dosing tank, and then injecting it into the ash pipe continuously or intermittently. This process requires additional cleaning equipment during shutdown, resulting in higher costs.
Continuous cleaning without shutdown
This process involves continuously injecting a certain amount of acidic solution while simultaneously introducing a specific quantity of slurry pipeline operation cleaning inhibitor and pipeline descaling agent, performing an open-loop cleaning. The main function of the cleaning aid is to promote the reaction between the acidic solution and scale in a solution with a certain concentration and flow rate, while also increasing its solubility in water, reducing the formation of air blockages, and ensuring the quality of the ash pipe cleaning.
The operation method is: First, estimate the required acid amount based on the total scale in the pipeline before cleaning. Then, calculate the acid addition rate and the flow rate for adding the descaling agent and pipeline cleaner based on the sludge water flow 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 the acidity by adjusting the acid flow rate. In the later stages of cleaning, collect 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 is efficient, cost-effective, non-damaging to workpieces, environmentally friendly, easy to operate, and safe.
Advantages of high-pressure water technology include:
(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 its immense energy and supersonic speed, the high-pressure water jet is fully capable of destroying tough 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) Rapid Cleaning Speed: Due to the combined abrasive actions of water jet flushing, wedging, shearing, and grinding, scaling can be quickly dislodged and removed, several to tens of times faster than traditional chemical methods, sandblasting and shot peening techniques, simple mechanical, and manual cleaning methods.
Components cleaned with high-pressure water jetting do not require secondary cleaning.

(3) Environmentally Friendly - As high-pressure water jet cleaning uses pure water as the medium, it does not generate a large amount of dust like sandblasting or simple mechanical cleaning, thereby not polluting the air and harming 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, being odorless, tasteless, and non-toxic, also helps to reduce the concentration of airborne dust in the work area after atomization, lowering the air dust levels from 80mg/m³ of other methods to below the national safety standards. Therefore, it does not cause any pollution.
Pipe Scale
(1) Classified by chemical composition, it can be divided 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.
(2) Classified by physical properties, there are two types: scale that is firmly adhered to the pot body and tube walls, and sediment that is loosely textured and easily detachable.
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, about 2 to 5 times that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it severely deteriorates heat transfer efficiency, affecting the boiler's performance; it can also cause metal materials to burn due to local overheating, potentially leading to pipe explosion accidents; it 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.
