Description	This paper deals with a comparison of pressurized thermogravimetric (TG) analyses of desulfurization with Cizkovice limestone under steady state reducing conditions at temperatures 800 and 900 oC and operating pressure 1 MPa with the same limestone under conditions of sub-stoichiometric PFBC of coals at air/fuel ratio = 0.75. Comparison of attainable degree of desulfurization in the PFBC and composition of solid product with theoretical predictions of desulfurization efficiency and with results of TG analyses has shown that desulfurization in sub-stoichiometric PFBC is more complicated involving formation and reduction of CaSO4.

(en) Náš příspěvek se zabývá srovnáním výsledků tlakové termo-gravimetrické (TG) analýzy odsiřování plynu pomocí Čížkovického vápence za stálých redukčních podmínek, teplot 800 a 900 oC, tlaku 1 MPa s výsledky odsiřování tímtéž vápencem za podmínek sub-stechiometrického TFS uhlí při poměru vzduch/vzduch-stechiom. = 0,75. Srovnání dosaženého stupně odsíření a složení tuhých zbytků po odsíření v TFS s výsledky TG analýz a teoretickým (rovnovážným) stupněm odsíření ukázalo, že odsiřování za podmínek sub-stechiometrického TFS je komplikovanější proces zahrnující tvorbu a redukci CaSO4.
