I is a unit-type power station. The 110 MW turbines are condensing, impulse, and three-casing turbines, with steam reheated in the boiler. Each turbine has seven steam extraction points for regeneration, and two steam extraction points for heat supply. Prun ov II is also a unit-type power station. The boilers are drum, dry-bottom boilers with natural circulation.
Powdered coal is blown directly into the furnace.
The boilers have diaphragm walls, steam reheating, and combustion air preheating in Ljungstr m type rotary heaters. The steam heats both the air for the boiler and the water for heating the power station. It is also used as a supply of heat to the towns in the area. As the Prun ov I and II stations are intended to continue full operation, they both have been desulphurized with the wet limestone washing method. The equipment for Prun ov II was a turnkey operation from a consortium of the Japanese firms Mitsubishi Heavy Industries and Mitsubishi Corporation, in co-operation with the Czech firm ZVU Hradec Kr lov , a.
