Stage 4 : Depressurizing 
Ash inside the vessel is emptied, the vessel is depressurized and the fluidizing valve closes, again the process is repeated from stage 1. the pressurized vessels feed to the conveying line, the automated control system maintains a constant conveying air mass flow in the pipeline, which prevents plugging and optimizes compressor operating power. Feeder units feed the line however in these system, material flows into the conveying line before the line is pressurized. It is a practical alternative for a vaccum system where headroom is limited.

This approach, blending the most efficient flow regimes offers advantages in reliability and reduced maintenance costs that can keep the system operating more efficiently.

Challanges of ash handling system

Indian Coal presents high ash content generally which tends to be inconsistent. Design of the system has to adequately cover anticipated variations and be capable of handling the worst scenario.

System has to be environment friendly.

System has to be reliable with least maintenance problems

System has to be energy efficient.
