What safety concern arises from burning black liquor?

The safety concern associated with burning black liquor primarily stems from the potential for violent explosions when it comes into contact with water. Black liquor is a byproduct of the pulping process, and it is highly concentrated, containing organic compounds and various inorganic materials. When water is introduced to black liquor, it can lead to a rapid and violent reaction due to the significant heat released and the generation of steam. This explosion risk can result in severe injuries and damage to equipment.

Understanding this aspect is crucial, as proper handling and precautions are essential when dealing with black liquor in a power generation context. The appropriate storage, transfer methods, and emergency procedures must be in place to mitigate these risks, emphasizing the importance of training and safety protocols in facilities that handle this material.
