Modelling of Fluidized Bed Hydrodynamics for a Ca-looping System
Original language description
This paper presents mathematical model of a Ca-looping (CaL) system based on detailed calculation of a circulating fluidized bed (CFB) hydrodynamics and chemical kinetics. The system is designed to capture CO2 from flue gas from 250 kWth pilot-scale combustor and consists of two CFB reactors, called carbonator and calciner. Both reactors are operated in a fast-fluidization regime where the fluidized bed creates a dense bottom zone and a lean upper zone. In a radial cross-section, the solids fraction decreases from a dense wall zone to the lean core zone according the core-annulus model. The CO2 capture efficiency depends on various parameters, but it is mostly affected by the residence time of active solids in the carbonator, which can be determined from the CFB hydrodynamics model. Detailed parametrization of the CO2 capture efficiency is presented within this paper.
