PCHEs boost power from waste heat Heatric recently supplied Echogen Power Systems Inc. with Printed Circuit Heat Exchangers (PCHEs) for Echogen’s Supercritical CO2 (ScCO2) power generation cycle. The power generation system converts industrial waste heat into electricity, using supercritical CO2 as the working fluid and without creating new emissions. Heatric’s PCHEs help transfer more of the waste heat into electricity than would be possible with non-supercritical fluids. In the Echogen system, liquid CO2 is pumped to supercritical pressure, where it accepts internally recycled heat at the recuperator, followed by waste heat from the hot flue gas supply (Fig. 1).
