Kriel is unique in that each turbine generator set is separate. The water is circulated through the system by 12 CW pumps situated in two pump houses between the cooling tower ponds. This steam is superheated to 516ºC at a pressure of 17,2 MPa and fed into the HP turbine where the heat energy is converted to mechanical energy. Our innovative process design and rapid construction programme meant that we were able to install a desalination system on the cooling tower feed water relatively fast. Three 50% Ammonex deep-bed polishers remove soluble impurities by an ion exchange process, also acting as a very efficient high-speed filter to remove insoluble crud. The city of Kimberley was one of the first users of public electricity when it installed electric streetlights in 1882 to reduce crime at night. [11] One of Eskom's first power plants was a coal-fired 128 MW station in Witbank completed in 1935 to provide power to the mining industry.

The Kriel Power Station is located just outside town. The grinding elements consist of a stationary upper grinding ring fitted with hydraulic tension rams, and 240ºC) to repeat the cycle .a lower rotating grinding ring fitted with hydraulic tension rams, and a lower rotating grinding ring spun at 32,8 r/min by a 3,3 kV GEC electrical motor through a reduction gearbox. 2 Disclaimer This report has been prepared by KPMG Services (Pty) Ltd (“KPMG”) exclusively for the benefit, information use of ESKOM for the exclusive purposes of/in order to assist ESKOM to estimate the socio-economic There are two varieties in use. In Eskom’s other power stations all the turbines are housed in a single turbine hall and placed along the same axis. In the event of the failure of running auxiliaries standby plant is automatically switched on. At maximum continuous rating (MCR) the steam feed pump delivers water at a rate of 415 kg/s at a pressure of 21,3 MPa.
