AB  - An overall model for sulfur self-retention in ash during coal particle combustion is developed in this paper. It is assumed that sulfur retention during char combustion occurs due to the reaction between SO2 and CaO in the form of uniformly distributed non-porous grains. Parametric analysis shows that the process of sulfur self-retention is limited by solid difussion through the non-porous product layer formed on the CaO grains and that the most important coal characteristics which influence sulfur self-retention are coal rank. content of sulfur forms. molar Ca/S ratio and particle radius. A comparison with the experimentally obtained values in a FB reactor showed that die model can adequately predict the kinetics of the process, the levels of the obtained values of the SSR efficiencies, as well as the influence of temperature and coal particle size.
AB  - U radu je prikazan razvijeni model zadržavanja sumpora u pepelu tokom sagorevanja uglja. Pretpostavka modela je da se zadržavanje sumpora tokom sagorevanja koksnog ostatka odigrava usled reakcije SO2 i CaO koji je u obliku ravnomerno raspoređenih zrna. Parametarska analiza je pokazala da je proces zadržavanja sumpora kontrolisan difuzijom kroz formirani sloj čvrstog produkta na zrnima CaO, kao i da su rang uglja, sadržaj formi sumpora molarni Ca/S odnos i veličina čestice važne osobine uglja koje utiču na proces. Poređenje sa eksperimentalnim rezultatima dobijenim u reaktoru sa fluidizovanim slojem je pokazalo da model može adekvatno da predvidi kinetiku procesa, efikasnost zadržavanja sumpora u pepelu, kao i uticaj temperature i veličine čestice uglja.
