Look at the size of the boiler, if it is a large boiler of a power plant.

There are really a lot of boiler cleaning mechanisms. It can be judged according to the following comments:

Choose an institution with the corresponding boiler cleaning qualification, such as boiler cleaning class A qualification, etc.;

Choose an organization with rich cleaning experience, such as cleaning boilers for many large power plants, etc.;

Choose an institution with a good reputation and see what everyone thinks of him online;

If you can, it's best to go on a field trip and know what to do.

Which one is better, no one can tell, I believe that after personal comparison, there will be an answer.

Scale is the biggest problem affecting the service life of the wall-hung boiler, it is best to put away the dirty water after using it for a period of time and fill it with new water.

The wall-hung boiler is generally cleaned once every two or three years, and the cleaning cost is generally about 100-300 yuan.

The difficulty of cleaning is not the same, but it is also different. The cost of wall-hung boiler cleaning is mainly labor cost, and the labor cost in different regions is also different.

For more information, please call us or make an appointment for cleaning.

This should only be determined by the cleaning company. The charge of the **** of the Fuyoude environmental protection project is relatively cheap, and it has been done in China for more than ten years, and it seems that it is necessary to determine the budget **, you go and ask the http: 736163897?qxgs

If you forgot your computer administrator password, use the second method or section.

Three or four methods.

Method (2) 1: Restart the computer, press the F8 button after booting up until the advanced options screen appears, then release your hand and select "Safe Mode of Command Prompt" to enter.

2. At the end of the running process, the system lists the selection menu of the system superuser "administrator" and the local user "**", and clicks "administrator" to enter the command line mode.

This should only be determined by the cleaning company. Kelly's cleaning company's fees are relatively cheap, and it has been done in China for more than ten years, and it seems that it can only be determined through the budget**, you can ask yourself.

Shenyang Wantong vigorously machinery, there are a lot of professional equipment.

Different furnace type, the size of the capacity, different cleaning agents, the content is quite a lot, I don't know what the line of pure luck is asking about that aspect of the beam style, if it is convenient, please check the "boiler cleaning guidelines" on the Internet.

Qianye Qingshen hand washing: due to the different water quality, the leakage of the scale potato is different, and the cleaning agent must be prepared according to the analysis and laboratory test of different scales, and then cleaned according to the boiler cleaning rules.

The benefits of Hongtai energy-saving and environmentally friendly industrial cleaning are as follows:

1. The boiler will run scale-free, greatly reducing fuel consumption;

2. Reduce boiler cleaning and maintenance costs;

3. Avoid potential safety hazards such as corrosion, bulging, deformation, leakage and even leakage caused by boiler fouling;

4. Greatly prolong the service life of the boiler;

5. Avoid losses caused by shutdown due to boiler cleaning or repair.

Boiler cleaning can effectively improve the thermal efficiency and service life of the boiler, so cleaning the boiler is not a trivial matter, so the boiler should be cleaned frequently! The cleaning of the boiler is divided into these steps!

Gas Boiler Cleaning Process:

1. Descaling and cleaning.

In the circulating water of the cleaning tank, participate in the equipped descaling and cleaning agent according to the share, and carry out boiler cleaning and descaling, and select the time of the cleaning cycle and the amount of participating agents according to the amount of scale, and transfer to the next cleaning procedure after confessing that all the scale is cleaned.

2. Wash with water.

The fullness project believes that after the cleaning equipment and boiler are connected, it should be cleaned with clean water for 10 minutes, check the condition of the system, whether there is any leakage, and clean the floating rust together.

3. Peel off and clean anti-corrosion.

According to the share, participate in the surface stripping agent and sustained-release agent in the circulating water of the cleaning tank, and circulate and clean for about 20 minutes, so that the scale and the cleaning parts are separated, and the surface of the object without scaling is treated with anti-corrosion, so as to avoid the corrosion of the cleaned parts by the cleaning agent during descaling and cleaning.

Fourth, passivation coating treatment.

Participate in passivation coating agents, passivation coating treatment of boiler cleaning systems, prevention and control of corrosion of pipelines and components, and the formation of new rust scale.

Scale is the primary culprit of boilers and the primary cause of boiler incidents. Because the thermal conductivity of scale is only a few tenths of that of steel, when the heating surface is fouled, the heat transfer will be blocked, and in order to maintain the certain power of the boiler, it is necessary to trek through the temperature on the fire side, which wastes a lot of fuel: so that the heat that radiates outward and exhausts the smoke is lost.

After the boiler is operated for a long time, there will inevitably be scale and rust problems. Because the hardness of water is different, through the continuous transpiration and concentration of high temperature and high pressure, a series of physical and chemical reactions occur in the furnace, after all, a calm and fine scale is formed on the heating surface, which leads to the decline of heat exchange and the corrosion elements under the scale, which will also lead to the reduction of heat absorption in the boiler water-cooled wall hearth, and the increase in the outlet temperature of the boiler furnace, so that the boiler will be lost. After the fouling in the water wall, the heat transfer is reduced, which may lead to the increase of the temperature of the water wall and the burst of the water wall, which will affect the safe operation of the boiler.

1. The acid used in boiler pickling is determined according to the composition of the scale.

2. The general-purpose type is hydrochloric acid, more sulfuric acid, sulfonic acid, citric acid, EDTA and so on.

3. Corrosion inhibitors must be added, and specific additives are made according to the type of acid.

If you have any questions, add q to communicate.

Anti-rust think tank, for you to answer.

Sulfamic acid is commonly used, and a sustained-release agent needs to be added during cleaning.

If the boiler is not cleaned for a long time, it will breed a large amount of scale, and the harm of scale to the boiler is huge

1. Due to the poor thermal conductivity of scale, it hinders the heat transfer to the working fluid, the heat absorption of the working fluid decreases, the boiler exhaust gas temperature rises and the heat loss increases.

2. Due to the poor thermal conductivity of scale, it hinders the heat transfer to the working fluid, and the working temperature of the thermal insulation surface of the receiving base increases, which will cause the superheater of the heating surface to burst the pipe or overheat the bulge in serious cases.

3. Corrosion: Natural water is an aqueous solution of electrolyte, which is easy to produce electrochemical corrosion in contact with metal.

4. If the salt scale is deposited at the valve of the steam, it may cause the valve to malfunction and the valve to leak.

Green Source Boiler Cleaner is mainly used to clean all kinds of boilers, electric boilers carbonate scale and calcium sulfate, calcium hydroxide, plus iron oxide and other mixed scale.
