What is the Reason for Black Smoke From Biomass Burner?
Some customers will emit black smoke when burning biomass burners, and the black smoke will definitely be considered unqualified by the Environmental Protection Bureau, so what is the reason?
The main reasons for black smoke generated by biomass burners are biomass pellet fuel, biomass combustion conditions, and improper operation of biomass burner.
1. Black smoke is caused by insufficient combustion of biomass pellet fuel, which is the reason most biomass burners produce black smoke. The poor quality and unreasonable design of biomass pellet fuel burners produced by some manufacturers lead to the combustion of biomass pellet fuel in the biomass burner, and the combustion of biomass pellet fuel will produce carbon dioxide, sulfur dioxide, water vapor, oxygen, nitrogen, and other gases. Combustible gases, such as carbon monoxide, hydrogen, methane, etc. It will also be produced. If biomass combustion is not sufficient, it will produce black smoke. These black smoke are actually combustible gases with calorific value. Incomplete combustion will not only affect the environment but also cause waste of biomass pellet fuel and increase the operating costs of enterprises.
2. Improper air distribution operation during the operation of biomass pellet burner leads to low furnace temperature. The combustion of biomass pellet fuel requires sufficient oxygen, so the air distribution of biomass burner is very important. Improper operation, the small air volume, and insufficient oxygen supply will lead to black smoke from combustion products.
3. The secondary air distribution of the biomass burner is insufficient, or some simple burners have no secondary air at all. The biomass fuel is first cracked and burned in the biomass burner and forms a combustible gas with the secondary air at the burner nozzle for secondary combustion. Therefore, if the secondary air is insufficient, it will cause insufficient combustion and black smoke.
4. Excessive moisture in the biomass pellet fuel burned by the biomass burner will also produce black smoke, mainly because the water vapor is large at the initial stage of ignition, and the mixed flue gas is easy to burn without penetrating, resulting in black smoke.
