HOT AIR CIRCULATION

Hot-air recirculation enhances the efficiency of the waste heat recovery system.
 
Most Waste Heat Recovery Systems (WHRS) operate by extracting hot air midway through the process. The higher the recuperation efficiency, the less heat remains available for the WHRS. With the IKN Pendulum Cooler®, the plant can prioritize either maximizing recuperation or maximizing WHRS output. Recirculation enables operators to adjust the vent air ratio and the amount of air allocated to the WHRS favorably. By maximizing heat extraction at the mid-point, WHRS output can be significantly boosted.
