How are shot cleaning pellets transported to the top of the boiler?

The correct method for transporting shot cleaning pellets to the top of the boiler is through the use of an air stream. This process utilizes compressed air to create a flow that carries the pellets upward. The effectiveness of an air stream for this purpose lies in its ability to create a constant and regulated movement, allowing for efficient and robust transportation of materials without the risks associated with other mechanical systems.

Using air as a transport medium minimizes the potential for damage to both the pellets and the boiler infrastructure. It also allows for a smoother, continuous operation, which is essential in maintaining an optimal cleaning process within the boiler system. The reliance on an air stream is common in many industrial applications, particularly for moving granular materials to heights where gravity alone would not suffice.

Other methods, like manual transportation, would be inefficient and labor-intensive, while hydraulic or steam injection systems would introduce complexities and potential safety hazards that are not present with the air stream method. Thus, the air stream approach not only simplifies the logistics but also enhances overall operational safety and efficiency.
