Systems, devices, and/or methods for recuperating energy and/or particulates

Abstract

Certain exemplary embodiments provide an energy and particle recuperator (EPR) for dirty gas fluids and/or gas solids fluid mixes. Gas fluids and/or gas solids fluid mixes stream through a vessel. Heat contained in the gas fluids and/or gas solid fluid mixes is partially transferred to a liquid spray fluid sprayed inside the vessel. Heat is transferred from the liquid to a clean process fluid via a heat exchanger.
