System Of Fly Ash And Bottom Ash Transport From Thermal Power Plant
New technology of hydraulic transport is based on the dense slurry in the mass ratio (fly ash: water - 1:1). The basic characteristic of this technology is that the water mixes with fly ash and bottom ash in the ratio in the form of dense slurry transporting by high pressure pumps and by pipeline to disposal area. Transport of fly ash and bottom ash slurry is carried out by three transport lines, two are operational and one is reserve. Each transport line starts from conditioner and consists of composite centrifugal slurry pumps, long distance steel pipelines and pipeline distributions around the depot. Hydraulic calculation refers to nominal transport capacity, maximum length of pipelines and maximum elevation head of unloading. By this calculation 4 pumps connected in line have been selected, according to high requirements of system performances. In this paper the description of system of fly ash and bottom ash transport from thermal power plant Nikola Tesla B in Obrenovac which is realized by company Energoinvest d.d. Sarajevo is given.
