Chemical cleaning descaling process:

Recirculating Closed Circuit Cleaning

Recirculating cleaning utilizes two original parallel ash pipeline lines to form a loop, creating a circulation system with the cleaning pump station. A certain concentration of acidic solution is added, and it circulates within the ash water pipeline for cleaning. Additionally, 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 during shutdown and is complex and costly.

Breakbulk Cleaning

No two gray pipes can form a loop during cleaning; only a single gray pipe can be used for open circuit cleaning. The method involves connecting one end of the gray pipe to the cleaning unit and continuously preparing a specific concentration of cleaning solution in the dosing tank, then continuously or intermittently injecting it into the gray pipe. This process requires the addition of cleaning equipment while the system is shut down, resulting in higher costs.

Continuous cleaning without shutdown

The process involves continuously injecting a certain amount of acidic solution while operating the ash conveying pipes, simultaneously introducing 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 ash deposits at a certain concentration and flow rate, while also increasing 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 for the ash slurry pipeline based on the flow rate of the grey water and the acidity. During cleaning, collect samples at the front end of the ash pipeline every 30 minutes to test the acidity, and strictly control it by adjusting the acid flow rate. In the later stage of cleaning, collect samples at the end of the ash 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 process can be considered complete.

2. High-pressure water jet cleaning equipment
High-pressure water jet cleaning offers high efficiency, low cost, non-damaging to workpieces, environmental friendliness, ease of operation, and safety advantages.
High-pressure water technology boasts the following advantages.

(1) Excellent Cleaning Quality - The high-pressure water jet cleaning of pipeline 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 destroying hard scale and blockages, yet it has no destructive effect on metal.

High-pressure water cleaning will not damage the base material to be cleaned, as the pressure is less than the tensile strength grade of metal.

(2) Fast Cleaning Speed: Due to the combined effects 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, 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 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, shot 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 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 causing no pollution.

3. Pipe Scale

(1) Categorized by chemical composition, they include carbonate scale, sulfate scale, silicate scale, and mixed scale. The main components of carbonate scale are calcium carbonate and magnesium carbonate; sulfate scale and silicate scale are primarily composed of calcium sulfate and silicate compounds, respectively. Mixed scale is usually a mixture of the above three types.

(2) Categorized by physical properties, there are two types: scale that is firmly adhered to the pot shell and tube walls, and sediment that is loosely textured and easily detached.
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, approximately 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, potentially 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.
