5.3.5  New Installation in Ventilation Heat Exchangers 

To completely remove the need for district heating, another investment also has to be made. 

The piping and heat exchangers for the heat exchange between the cooling water and the 

ventilation inlet in three of the aggregates was only a temporary solution to reduce the need 

for district heating. The piping would need to be substituted with corrosion resistant tubes 

making it a permanent installation. If this is not done, an additional 262 MWh/year of district 

heating will be needed in the plant.
