Brief Description of Main Solutions

The object main purpose is the electric power generation in the generator, actuated by the condensing steam turbine, with the use of the steam supplied from the steam boiler where the wooden chips are fired. The main and standby fuel is the wooden chips.

The main production area includes the main building with the power output system and the fuel acceptance unit.
The auxiliary production area includes cooling towers, packaged transformer substation (2nd turn), auxiliary building with administrative – personal service rooms, fire-fighting system, turbine oil emergency discharge tanks, treatment plants and wooden chipping complex (2nd turn).

The storage production area includes the wooden chips store, truck pass-through, weigh station, being within the scope of the 2nd construction turn.

The steam boiler is single-drum, with vertical-water tubes, of natural circulation, with rotating fire grating.
