Biomass boiler as a new type of environmental protection equipment, not only to a large extent to reduce pollution emissions, but also save costs, mainly because the biomass boiler raw materials are waste wheat straw, rice husk, bark, etc.A few customers encounter black smoke in the process of using biomass boilers, how is this going on?Huatai Boiler believes that there may be the following reasons:

1. Insufficient combustion.The main cause of black smoke boiler is due to insufficient fuel combustion, when the boiler is in operation, because the fuel has not been fully burned, in addition to CO2, O, N and other gases, but also produce CO, H, methane and other combustible gases, these combustible gases in the side produced black smoke.

2. Insufficient air volume.May be because the air volume is insufficient and the temperature in the furnace is low, the general biomass boiler will be equipped with air preheater, and when the air preheater has serious air leakage, the hot air volume can not meet the conditions required for combustion, so as to appear the phenomenon of black smoke.

3, cleaning is not timely.There may also be no timely cleaning furnace residue, or use time is too long, resulting in smoke pipe blockage.

4, chimney installation is not reasonable.In the installation of the boiler chimney structure is not reasonable, leading to the increase of flue resistance and other reasons.

In this regard, what measures can prevent the black smoke of biomass boilers?

Boiler feeding should be reasonable, too much feeding will lead to pressure fire, fuel can not fully combustion.Try to increase the air temperature and the temperature in the furnace.Appropriate air supply operation, so that the oil mist and air normal fusion, to prevent local hypoxia phenomenon.Timely to the furnace ash, boiler chimney cleaning work.

Well, the relevant knowledge about the black smoke of biomass boiler, Huatai boiler is shared here, I hope to help you.
