✦ Synopsis
the behaviour of a pilot-scale fluidized-bed combustor, followed by comparison of its predictions with measurements and also with the results predicted by the previous code. The computer code replaces the conventional numerical integration of the analytical solution of population balance with direct integration in ODE form, by using a powerful integrator LSODE. This results in a reduction of CPU time by two orders of magnitude. For the prediction of physically expected variation of char holdup with excess air, an energy balance on char particles must be incorporated into the system model. When the predicted and measured temperature and concentration profiles were compared they proved that the present code produces better agreement than the previous one in bed-concentration profiles.
