Recirculating closed-loop cleaning
Recirculating cleaning utilizes two original 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 through the ash water pipes for cleaning. As the acid washing reduces to a certain level, the solution is continuously replenished with acid. 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 during shutdown and is complex and costly.

Pilot 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 mixing tank, and then continuously or intermittently injecting it into the ash pipe. This process requires adding cleaning equipment while the system is offline, which increases costs.
Non-stop 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 cleaning descaler 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 enhancing its solubility in water, reducing the occurrence of air blockages, and 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 operation by considering the sludge flow rate and acidity. During cleaning, take a sample at the front end of the sludge pipeline every 30 minutes to test the acidity and strictly control it by adjusting the acid flow rate. In the later stage of cleaning, take a sample at the end of the sludge pipeline 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 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 method for pipes and heat exchanger bores can thoroughly 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 breaking down hard scale 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 material being cleaned.
(2) Fast Cleaning Speed: Due to the combined action of jet washing, wedging, shearing, and grinding, scaling can be quickly broken and removed, which is several to ten times faster than traditional chemical methods, sandblasting and shot peening 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 rinsed with clean water.

(3) Non-polluting: Since high-pressure water jet cleaning uses pure water as the medium, it does not generate a large amount of dust like sandblasting, shot blasting, or simple mechanical cleaning, which can pollute the air and harm health. It also does not produce a large amount of waste liquid like some chemical cleaning methods, which can pollute rivers, soil, and water quality. The water jet cleaning using pure water is odorless, tasteless, and non-toxic. After atomizing the jet, 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 causing no pollution.

Pipe Scale
(1) Classified by chemical composition, they can be categorized into carbonate scale, sulfate scale, silicate scale, and mixed scale. 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.

(2) Classified 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 dislodge.
Lime scale primarily forms due to the salts like calcium and magnesium in the boiler feedwater, which precipitate and adhere to the metal surface upon heating. The thermal conductivity of lime scale is very low, approximately 2 to 5 times less than that of ordinary steel. Lime scale on the boiler heating surface severely deteriorates heat transfer efficiency and affects the boiler's performance; it can easily lead to the burning and even bursting of pipes due to localized overheating; it also accelerates galvanic corrosion, causing pipeline lime scale corrosion and hastening the damage to the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
