The conversion of the
chemical energy contained in fuel into thermal energy takes place in
the boiler furnaces. The thermal energy of steam is converted into
mechanical energy in the steam turbines and the electrical generators
convert the mechanical energy into electricity. These three systems
represent the major processes and without any of them, the production of
electricity is not possible, the shutting down or malfunction of one of
them means that production at the plant will grind to a halt.
To keep production running smoothly a number of other installations
are required. With these devices we supply the coal for the plant,
remove the by-products of burning and desulphurisation to the landfills,
prepare the decarbonised water for steam cooling, the feed water for
the boilers, provide the hydrogen and oxygen for generator cooling and
we also supply the entire Šaleška valley district with heating. The
operation of these installations can, in contrast with the major
systems, be stopped for a short while without compromising the operation
of the plant. These devices operate by accumulating reserves in
reservoirs or silos (water, gasses, coal, petroleum, heavy fuel oil,
calcite powder, ash, slag, wet gypsum etc.).
