AI Technical Summary
In traditional powder feeders, high-pressure air can easily seep into the material storage tank, causing unstable material flow and preventing continuous and uniform discharge. This affects the stable combustion of the burner, leading to equipment malfunctions and safety hazards.
A novel SPC solid pellet fuel feeding device was designed, which uses a semi-circular high-pressure air lock plate to block airflow, combined with a stirrer and impeller structure to ensure that the material falls and disperses naturally. High-pressure air is used to drive the material conveying, preventing air pressure turbulence and achieving continuous and uniform discharge.
It effectively prevents air pressure imbalance, ensures continuous and uniform material discharge, provides a stable fuel supply, improves equipment operating efficiency and safety, and avoids equipment failure.
