Abstract:
A detailed model for flue gas desulfurization by spray-dry absorption with calcium hydro agent is presented. The model refers to a steady state one-dimensional model by means of infinitesimal analysis, incorporating with the model of droplet evaporation, shrinking core and sulfur absorption. The trends of moisture, temperature field, SO2 and vapor concentration along the axial direction are calculated and the results are compared with the experimental data. It is shown that applying multi-level humidifying, the temperature field in the riser gets more tempered and the outlet temperature is 3 to 6℃ lower comparing to 1-level humidifying; As the droplet evaporation gets slower, the desulfurization efficiency increases by 7% to 11%; The total droplet mass in the riser is found to be very important factor for the sulfur removal efficiency and it is of reference value for the design and operation of the humidifying system.
