Water spray feed rate is adjusted by control valves. The conveying action provided by the rotating paddles provides continuous flow of uniformly mixed ash with no excess water or dusting. SLURRY DISOPOSAL AND ASH WATER RECOVERY SYSTEM : SLURRY DISOPOSAL AND ASH WATER RECOVERY SYSTEM SILO SLURRY PUMP SETTLING POND STILLING POND VERTICAL TURBINE PUMP CLARIFLOCULATOR ASH WATER TANK SLURRY PUMP : SLURRY PUMP Horizontal, centrifugal type Capacity = 450 m3/hr No. of pumps = 3(2W+1S) SETTLING AND STILLING POND : SETTLING AND STILLING POND Provided with HDPE 70% of water can be recovered Slurry settles due to residence in settling pond Partial clear water then goes to stilling pond Remaining ash settles in stilling pond VERTICAL TURBINE PUMP : VERTICAL TURBINE PUMP Used wherever a liquid need to be pumped upwards Used to moderate to high pressure applications Used in open bodies of liquids such as oceans, lakes, cooling ponds. CLARIFLOCCULATOR : CLARIFLOCCULATOR Combination of Clarifier and Flocculator Suspended solids limited to 20ppm Clear water is led to Ash Water tank CONTENTS You do not have the permission to view this presentation.
