Circulating fluidized bed calciner model for a Ca-looping system
Original language description
A theoretical model of circulating fluidized bed calciner for a Ca-looping system for 200 kW pilot scale facility is presented in this paper. The oxy fuel combustion of coal is proposed for the supply of heat needed for endothermal calcination reaction. Based on the heat balance and the material properties of internals the reactor dimensions are suggested. The input parameters such as temperature, material flows and mass of solids are chosen in order to obtain the best calcination efficiency using the calcination reaction kinetics. The results show that if the high purity of outlet gas is required (volumetric fraction of CO2 higher the 0.9), the temperature will have to be at least 1170 K, which indicates a feasibility for a HRSG application. This model is prepared for an integration in a whole Ca-looping system computation including the heat balance of HRSG.
