Process design of the Phola coal J preparation plant o
The design of the Phola coal preparation has its roots in the late 1980s when there was a requirement for a plant to treat 8 Mtpa coal from Ingwe's (now BECSA's) adjacent Klipspruit opencast mine at Ogies, Mpumalanga. The mine is part of the South African Witbank Coalfield and accesses the No. 2 and 4 Seams with some 5 Seam material.

How a Coal Plant Works
How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
