Figure Pneumatic system Mechanical system Figure Mechanical system Figure shows a mechanical ash handling system In this system ash cooled by water seal falls on the belt conveyor and is carried out continuously to the bunker The ash is then removed to the dumping site from the ash banker with the help of trucks...

The ash from the fluidiesd bed the cyclone and the ESP is conveyed pneumatically to the main ash silo keeping the plant clean of ash The boiler is designed with fluidising velocities up to 45m/s generating a high turbulence and resulting in a good mixing of hot bed material with fuel and recirculated fly ash The height of the bed is kept...

The system The fuel and the cold fly ash recirculated to the fluidised bed is well mixed with the hot This is achieved by higher turbulence caused by introducing fluidising air in smaller bed dimensions Unlike Bubbling AFBC boilers erosion-prone submerged heating surfaces are dispensed Ash Handling Wet Dry Dry System very simple...

Mechanized ash handling systems developed as the size of coal fired boilers increased beyond the sizes permitting manual handling of large quantity of ash In a coal based thermal power plant huge amount of ash is generated which has to be disposed off continuously Typically for a 2x500 MW plant based on Indian coal the amount of ash...
