At the Warkworth BDT Fuel Preperation Plant, the coal tailings are
dewatered at four Jameson Cells centrifuges with 5 metre diameter each
The coal tailings (BDT) are deliverd to the Power Station via a 3,8 km
conveyor at 80 tonnes/ hour. The conveyor is covered to keep the BDT`s dry…
The Boilers work with a steam pressure of 10,600kp,a at a steam
temperature of 510°C, firing predominately (BDT), working with mine coal
as back up…
The steam turbine has a single cylinder, condensing in two stages with
axial flow exhaust, operates at a speed of 3,000rpm and is 25 meteres
long…
The six cooling towers have a capacity of cooling 400 megalitres per day
of water throughout, the diameters of the fans is 9,1 meters…
The evaporation of the cooling water, which is discharged into the Hunter
River and thus given back to nature as warm water, is 7,5 megalitres/day…
When on-site, I observed a truck with the safety sign: “Hypochlorite; UN
No: 1791; HAZEM: 2X” entering the power plant. Was it delivering or
collecting?..
The whole process commenced electricity generation in February 2001,
supplying enough electricity to power a typical Australian city of about
100,00 people. In official, public distributed brochures, it is labelled
as beeing:”…pinoneer of advanced, environmental sensitive technology…”.
That sounds all very good, however, everybody is asked to make up his or
hers own mind about the advantages of this method to produce electricity
and supply it to the grid…
