IE Questions: Can We Turn Power Plants Wasted Heat Into

Jun 20, 2016· To simplify a bit, Garrett is interested in the waste heat created when energy is produced in a power plant. Can it be reused? Recycled? Turned into energy? He got the idea from his uncle, who runs two gas turbine plants in Louisiana. My uncle, he showed me around one day and showed me how his power plants work, Garrett said.: Catherine RobertsWaste Heat Recovery For Desalination From Steam Power Plantshttps:// 17, 2014· The COP of the heat pump may be enhanced by multi-staging and/or economising of the compressors plus perhaps the addition of a Mechanical Vapour Recompression (MVR) stage at the front end of the MED plant. Conclusions. Using heat pumps to condense steam in Steam Power Plants (SPPs) allows the recovery of waste heat at high efficiency.
