Ash Vessel System - Cast Iron, High Pressure Dense Phase Pneumatic Conveying | Pressure Tight Dome Valve, Inflatable Synthetic Rubber Seal, Batch Conveying Mode

The Ash Vessel System operates on the principle of Dense Phase Pneumatic Conveying, i.e. a high pressure, dense material air mixture at a low velocity moving through the conveying pipe in separate batches or plugs. The Ash Vessel comprises one piece body with a top inlet aperture and horizontal inlet and outlet aperture for conveying material. Mounted on the top inlet is a specially designed Macawber Beekay Dome Valve. It has a controlled air supply for conveying the material.

The Dome Valve is a pressure tight valve. It comprises of a cast iron body, a movable part spherical dome, support shafts and bearing, and integral inflatable synthetic rubber seal, a pneumatic cylinder actuator and an air limit switch to operate the inflatable seal. The air limit switch is arranged such that the dome must be closed before the seal can be inflated, the seal being deflated before the dome is opened. The inflatable seal is so arranged that it closes tightly on to the outside face of the dome thus providing an air tight seal into the valve body.
