Ash Vessel By Macawber Beekay Pvt. Ltd.

The Dome valve is normally closed, when material transfer is required, the Dome valve opens and allows the material to be vessel filled in Dome valve closes through timer, and the pneumatic seal inflates against the Dome and at the same instant the vessel is pressurized by high pressure of air, material resistance causes a pressure build-up in the vessel which conveys the complete charge to the storage bunker or silo. When conveying is completed the pressure drops down to near atmospheric pressure and is sensed by the control system, the air supply to the vessel is stopped and the Dome valve opens to accept the next charge of material, on the command from level probe/timer.

The Ash vessel is used where material from number of hoppers is collected in different ash vessels and is conveyed through a single pipeline. All the ash vessels are connected in series have independent dome valve, but the conveying air is controlled by first vessel i.e. called Master Vessel. The other vessels are called Slave Vessels.
