By integrating water/water or water/air heat exchangers into scrubber circuits, large amounts of energy from the exhaust air can be transferred as useful energy into secondary water circuits or outdoor air. As a result, interesting amortizations can also reduce costs for exhaust gas cleaning systems.
Especially in exhaust gas cleaning systems with condensation heat recovery systems, the heat decoupling results in economic operating costs reductions for combustion air preheating, process heating or building heating.
If integrated into the local infrastructure, the energy thus recovered can also give the opportunity to act as an energy supplier. Another area of application is the heat shift by means of gas/gas heat exchangers.
