Abstract
In a retrofit system for hot solids combustion and gasification, a chemical looping system includes an endothermic reducer reactorhaving at least one materials inletfor introducing carbonaceous fuel and CaCOtherein and a CaS/gas outlet. A first CaS inletand a first CaSOinletare also defined by the reducer reactor. An oxidizer reactoris provided and includes an air inlet, a CaSO/gas outlet, a second CaS inlet, and a second CaSOinlet. A first separatoris in fluid communication with the CaS/gas outletand includes a product gas and a CaS/gas outletandfrom which CaS is introduced into said first and second CaS inlets. A second separatoris in fluid communication with the CaSO/gas outletand has an outletfor discharging gas therefrom, and a CaSOoutlet from which CaSOis introduced into the first and second CaSOinlets. The chemical looping system is in fluid communication with at least a portion of an existing power generation system.
