When coal is gasified in situ in the fuel reactor, several parameters affect the coal conversion, and hence the capture and combustion efficiencies. In this paper, a mathematical model for the fuel reactor is validated against experimental results obtained in a 100kWth CLC unit when reactor temperature, solids circulation flow rate or solids inventory are varied. This is the first time that a mathematical model for Chemical Looping Combustion of coal with in situ gasification (iG-CLC) has been validated against experimental results obtained in a continuously operated unit. The validated model can be used to evaluate the relevance of operating conditions on process efficiency. Model simulations showed that the reactor temperature, the solids circulation flow rate and the solids inventory were the most relevant operating conditions affecting the oxygen demand. However, high values of the solids circulation flow rate must be prevented because they cause a decrease in the CO2 capture. The high values of CO2 capture efficiency obtained were due to the highly efficient carbon stripper. The validated model is a helpful tool in designing the fuel reactor to optimize the CLC process. A CO2 capture efficiency of ηCC=98.5% and a total oxygen demand of ΩT=9.6% is predicted, operating at 1000°C and 1500kg/MWth in the fuel reactor. © 2013 Elsevier Ltd.This work was partially supported by the European Commission, under the RFCS program (ECLAIR Project, Contract RFC-PP-07011), Alstom Power Boilers, and the Spanish Ministry for Science and Innovation via the ENE2010-19550 project.
