Causes of breakdown of the Botu wall-mounted boiler

The Botu wall-mounted boiler is a relatively common heating boiler on the market and is widely used in household and personal use. However, even for a brand as well-known as Botu, it is inevitable that some malfunctions will occur. Here are the causes of common breakdowns of Botu wall-mounted boilers:

1. Water pressure is too low or too high: Water pressure that is too low or too high is one of the common Botu faults. wall-mounted boilers. When the water pressure is too low, there may be no hot water and when the water pressure is too high, the safety valve may release the pressure.

2. Hot water is not hot or not producing hot water: When the hot water from Botu wall mounted boiler is not hot or hot water is not coming out, it is usually due to condensate. the pipe is clogged or the water pump is damaged. In addition, if the boiler does not havebeen cleaned for a long time, it will also cause the problem of hot water not hot or no hot water coming out.

3. Poor combustion or fire leakage: Poor combustion or fire leakage are also common faults of Botu wall-mounted boilers. This situation is often caused by fuel pumps, fuel taps, nozzles, etc. obstructed.

4. Boiler noise is too loud: If the Botu wall-mounted boiler is making excessive noise, it is probably due to a fault or wear of the water pump, fan, burner and other components.

5. Boiler leaking: If the Botu wall mounted boiler is leaking, it is usually due to aging pipes, poor welding, damaged joints and other factors.

In short, there are many causes of Botu wall-mounted boiler failure, and various possibilities should be considered holistically.THE. If a malfunction occurs, users should promptly contact professional maintenance personnel for inspection and repair.

What is the reason for water leakage in the flue of the steam boiler?

“Fire extinguishing” or “fire extinguishing” of the boiler generally refers to: the fluid in the furnace instantly changes from the combustion state to a temperature below the temperature of inflammation. The unit of “snapshot” here must be. milliseconds, and the quantitative temperature change is hundreds of degrees or even thousands of degrees. This phenomenon often occurs in pulverized coal boilers. In a circulating fluidized bed boiler, the bed temperature does not change at the same rate as in the furnace cavity of a pulverized coal furnace. Therefore, in “Accident Analysis and Handling” of “Flow Bed Boiler Operation Guidelinesidized circulation class 135 MW”. , there is no " "Extinguish the fire" or "extinguish the fire". The expression "fire extinguishing" or "fire extinguishing" mentioned here must refer to "the temperature of the bed drops sharply

(1) The “fire extinguishing” phenomenon is as follows: 1) The bed temperature drops sharply and the smoke temperature drops 2) The combustion chamber goes from clear. to dark. 3) Main steam temperature and pressure drop. 4) Oxygen level indication increases significantly. (2) Reasons for “fire extinguishing”: 1) Power supply failure. coal or coal blockage, the coal stopping time is too long 2) The amount of slag dumped at one time is too large 3) The coal quality deteriorates suddenly, causing fire and poor combustion. 4) Malfunction (3) Treatment measures: 1) If all supply lines.ion to coal fail, the oil burner should be installed immediately and the primary and secondary air volume, load, heat exchange quantity of the external heat exchanger and cooling water volume should be adjusted at the same time. time ; the bed temperature should return to normal until ignition occurs above temperature and the coal feed line failure is cleared, the coal can be added slowly again according to the "jog" method, the coal must first be added with "air"; "coal". 2) If part of the coal supply line fails, the primary and secondary air volumes should be adjusted appropriately, adjust the load, adjust the heat exchange quantity of the heat exchanger external and adjust the amount of desuperheat water; once the bed temperature is stable and power failurein coal is eliminated, the coal feed line can be restored and the amount of coal feed. can be increased slowly; When adding coal, the "wind" should be added first. Add the “charcoal” later. 3) If the bed temperature drops suddenly due to the deterioration of coal quality, the fluidizing air volume should be reduced appropriately, the load and heat exchange rate of the external heat exchanger must be adjusted and the quantity of desuperheat water must be adjusted if; the bed temperature continues to drop, an oil burner can be installed; Improve coal quality conditions. 4) The principle of slag discharge is multiple and small quantities, and it is as continuous and stable as possible. Operation below the specified minimum bed pressure is strictly prohibited.

An analysis document on the causes of extinctionof fires in pulverized coal boilers

You have not clearly explained the problem and you have not mentioned the boiler model. How can someone help you analyze the causes? From what you have said the boiler must be a combination boiler (water and fire tube). The leak from the pyrotechnic tube was an accident. You should know that the pyrotechnic tube in the drum is not only the main heating surface, but also the main heating surface. main component of pressure. I don't know if the pyrotechnic tube in your boiler leaks when it is running? Or is the pyrotechnic tube leaking after repairing the boiler? (Of course, there are also water quality problems that cause pyrotechnic tubes or water-cooled wall tubes to leak after limescale corrosion)…. . Hualing Technology

There are several possible reasons for incens going outdie: 1. The influence of the type of coal, the type of coal used deviates significantly from the type of coal designed

2. The influence of air distribution and coordination of air and powder out of proportion

3. The boiler tube exploded and a large amount of steam and water entered the furnace, causing the fire to extinguish.

4. Factory power went out

5. No fuel

7. The removal and coking operations caused a large amount of cold air to leak into the oven

8. Large chunks of coke at high altitudes fell from the slag

9. Malfunction of fire protection
