Desulfurization under Conditions of Substoichiometric Pressurized Fluidized Bed Combustion of Coal - Comparison with TG-Tests and Equilibrium Limits.

Popis výsledku v původním jazyce

Our contribution deals with comparison of pressurized TG analyses of desulfurization by means of Cizkovice limestone under simulated, steady state reducing conditions, temperature 800 and 900 oC, operating pressure 10 bar (1,0 MPa) with results on pressurized fluidized bed combustion (PFBC) of selected coals with 'in situ' desulfurization by the same limestone at similar conditions. Sub-stoichiometry of PFBC of coal was characterized by air/fuel ratio 0,75. Comparison of attainable conversions of Ca inlimestone, attainable degree of desulfurization and theoretical predictions of desulfurization under reducing conditions reveals, that the process of desulfurization in substoichiometric PFBC with air/fuel ratio > 0,7 is more complicated and for description of the process reaction mechanism and path involving formation and reduction of CaSO4 have to be considered. The attainable degree of desulfurizations are currently higher in sub-stoichiometic PFBC than predictions derived from theore
