| Popis: | Chemical looping combustion (CLC) is an indirect combustion process in which a carbonaceous fuel is combusted without direct contact with air. Rather, transfer of oxygen between air and the fuel takes place with the aid of an oxygen-carrier (OC) material, yielding a CO2 stream of very high purity. This process is attractive for CO2-capture applications because it does not require additional energy to separate CO2 from N2, as in postcombustion CO2-capture processes. In this work, a mass and energy balance model has been developed to estimate the performance of a CLC system using different OC materials. To simplify the calculations, the specific heats of all gases and solids were assumed to be constant over the range of temperatures considered. The model was then applied to evaluate the effects on system performance of several design and operating parameters using three different OC materials. Given input conditions such as fuel, reactor operating temperature, fuel and OC material, the model calculates the ... |
