How to clean the boiler chimney, how to clean the stove chimney

Through the special equipment system, the water is generated by multi-beam, multi-angle, high-pressure water jets of different intensities to clean the boiler chimney. The internal scale, blockage or surface attachment of the cleaning object is thoroughly cut, crushed, extruded and washed to achieve the purpose of complete cleaning.

Structural deposits such as rust, iron oxide scale, resins, chemical residues, paints or epoxy resins can be cleaned with high-pressure water jet cleaning equipment to remove them and reveal their metallic color. No chemicals, solvents or corrosives are required, making it safe and environmentally friendly.

The blockage of the heating surface of the boiler air preheater, water wall, superheater, economizer and other heating surfaces will cause the exhaust gas temperature to increase, the boiler efficiency to decrease, and the consumption of induced draft fans to increase; Serious blockage will cause the fan to be unable to pull the negative pressure, the oxygen content of the furnace is not enough, and the boiler will be forced to shut down. Using high-pressure water jet technology, the cleaning effect is very obvious.

Extended Information: Precautions for the use of boilers:

1. The gas boiler should be inspected every 2-3 weeks.

2. After the gas boiler runs every 3-6 months, the furnace should be shut down for comprehensive inspection and maintenance

1) Inspect the inside and outside of the gas boiler, such as the weld of the pressure part, whether there is corrosion inside and outside the steel plate, if serious defects are found, they should be repaired in time, if the defects are not serious, they should be repaired when the furnace is stopped next time, if there is something suspicious, but it does not affect the safety of production, it should be recorded for future reference.

2) After the inspection, the boiler primer can be applied on the water surface to prevent corrosion.

3. Gas boilers and boiler bases should be painted at least once a year.

4. The maintenance method of gas boiler is not used for a long time: there are two kinds of dry method and wet method, the furnace should be stopped for more than one month, the dry maintenance method should be adopted, and the wet maintenance method can be used for less than one month.

Clause. 1. Mechanical ash removal, find a rope of sufficient length and sturdy, not too thick, tie an iron stone at one end of the rope, and then tie something similar to the bristles next to the iron stone, such as straw, weeds and other soft and hard things, and put the iron stone end from the chimney mouth to pull back and forth.

Clause. Second, if the chimney is small, you can also use that kind of wind-powered fire extinguisher to smoke or drum.

Clause. 3. If the machinery is inconvenient to remove the ash from the chimney, you can also use chemicals, in the general coal-fired additive plant, such as the production of accelerants, desulfurizers and other production plants have ash removers, according to the manufacturer's instructions to add to the coal, will also achieve ideal results.

Clause. Fourth, remove the chimney, use a special wire brush to poke the chimney in the smoke pipe, and then remove the dust.

The cleaning method of the furnace chimney is: if it is inconvenient to remove the ash from the chimney, you can also choose to use chemicals, in the general coal-fired additive factory, such as the production of accelerants, desulfurizers and other production plants have ash removers, according to the manufacturer's instructions to add to the coal, will also achieve ideal results.

The smoke is discharged directly from the roof of the house from the smoke outlet of the chimney. This method exhausts the smoke smoothly, and the pumping force of the furnace is relatively large, and the furnace is easy to burn very strongly. If you are afraid of rain falling into the chimney, you can add a rain cover on it.

If it is inconvenient to go out from the roof or you are afraid of rain leakage on the roof, you can choose to go out horizontally, and try not to choose the direction of the wind.

Add an elbow to the air outlet. A more effective way is to use a tee instead of an elbow. The most effective way is to install an induced draft fan at the air outlet, which is to consume some electricity and be more troublesome to connect the wires.

With a rope, thread the chimney through the hearth. Tie a cloth lump in the middle of the rope, and one person at the mouth of the hearth and one person at the outlet of the chimney, and pull the chimney with the cloth lump.

My dear, I will answer your questions for you, I hope it can help you! The best way to remove boiler smoke, boiler flue gas dust removal in China, in the early days, cyclone dust collectors, multi-tube dust collectors and wet dust collectors were used more, and later the use of electrostatic precipitators gradually increased. Recently.

With the further improvement of environmental protection requirements. Not only are inefficient multi-tube dust collectors and slightly more effective wet dust collectors far from meeting the requirements, but even efficient electrostatic precipitators are also feeling overstretched. In this case, according to foreign experience, the solution is to put the bag filter on the field.

Therefore, after entering the 21st century, the use of bag filters for boiler flue gas purification in China has gradually increased. The bag filter is a dust collector that can be operated by connecting the air duct and power supply, the size of this dust collector is small, no manual operation is required, the air volume is 1000-6000m3 h, and the filter wind speed is as follows: 740 filter cloth is used. 8m min, if the felt filter material is used.

1. The accuracy of the selection determines the size of the investment and the size of the filtration wind speed, 2. Whether the design is reasonable determines the pressure loss and the convenience of operation in the filtration process, 3. The selection of the accessories pulse valve (most of the ASCO is selected depends on the working conditions of the filter bag material. The bag filter is suitable for dust removal at scattered small air volume dust points, and the selection and process layout are simple. The dusty gas passes through the ash hopper (without which will go directly into the bag chamber) into the filter chamber with the filter bag.

The dust adheres to the outer surface of the filter bag, and the purified gas enters the upper box from the filter bag, and then discharges to the atmosphere by the fan through the exhaust pipe. With the thickening of the filter bag, the resistance of the dust collector continues to rise, and it is generally 1500pa when the upper auspicious or key rises to a certain extent), in order to ensure that the dust collector continues to work, the ash needs to be cleaned. The dust collector filter bags are arranged in a straight line, and each row of filter bags is equipped with a pulse valve to control the compressed air pulse cleaning, and the action of the pulse valve is controlled by the program controller.

When cleaning, the cleaning controller sends out a command to release the compressed air from the pulse valve at the moment of action. The compressed air rushes into the filter bag at high speed through the small hole on the blowing pipe facing the filter bag, and at the same time it rushes into the inside of the filter bag, it induces a secondary air flow several times that of the compressed air, so that an instantaneous shock wave is generated and propagates downward along the entire length of the filter.
