The black smoke from the boiler in my factory is very serious. I have tried many methods but cannot control it. Can you guys give me some advice? Thanks! By the way, the boiler in our factory is wood-fired. urgent!
Black smoke from the boiler may be due to insufficient combustion, so the air supply volume can be increased. It may also be that the fuel itself produces a large amount of black smoke after burning. I don't know if adding a dust collector can solve the problem.
Insufficient combustion, improve combustion conditions. You can contact the manufacturer
The main reason why the boiler emits black smoke is: 1. Insufficient combustion. The following aspects. a. Insufficient air supply. b. The combustion time of the flue gas is not enough. c. The aerodynamic field in the furnace is unreasonable. d. There is a problem with the air distribution adjustment of each section during boiler combustion. 2. The furnace temperature of the boiler is not enough. Carbon black is produced. 3. Selection of dust collector. (Processing energy, usage efficiency, etc.).
There may be a problem with the nozzle, causing insufficient combustion.
Brothers upstairs, where does the nozzle come from for the wood-burning boiler? This may still be insufficient combustion, resulting in carbon black.
The boiler mentioned by the poster is wood-fired. There should be no nozzle.
Insufficient combustion, increase air distribution.
It should be that there is insufficient oxygen. You can increase the air distribution volume and analyze whether the media quality is qualified.
The most likely cause is insufficient combustion! ! Also, the firewood may be wet! Take a look at what you should know based on the actual situation!
The poster should explain what type of boiler it is
I would also like to ask you for advice on the problem of insufficient combustion and black smoke.: When I started using diesel when lighting the stove, a lot of black smoke came out. How can I control the smoke?
It should be that the type of furnace is wrong. When the fuel changes, the furnace should be adjusted accordingly to avoid this problem.
Just distribute the air multiple times to ensure sufficient combustion.
1. Modify the air distribution and increase secondary air 2. Control the quality and stability of firewood 3. Maintain an appropriate furnace negative pressure 4. If the combustion is insufficient, increase the air volume appropriately 5. Modify the dust collector 6. Strengthen the operating level of the operator
Black smoke should be caused by incomplete combustion producing carbon black, which can be improved by considering reasonable air distribution and increasing secondary combustion.
