Heat exchangers for heat recovery
For residual heat recovery, we use heat exchangers that transfer residual heat to cold air streams (gas/gas heat exchangers) or heat exchangers that transfer residual heat to cold water or thermal oil (gas/liquid heat exchangers). The composition of the flue gas determines what material the heat exchanger is made of: metal or polymers. For corrosive or highly polluting flue gas, we opt for a polymer heat exchanger.
