FEIJOO CARABALLO, Javier Alejandro; FABELO FALCON, José A.  and  RODRIGUEZ RICO, Iván L.. Sulphur cycle assessment in the Cienfuegos cement factory kiln. cen. az. [online]. 2017, vol.44, n.2, pp.1-9. ISSN 0253-5777.

In this article a preliminary assessment and analysis of the kiln system of Cienfuegos Cement Factory was made focused on one of the most serious problems of the entity kiln area, due to unnecessary shutdowns caused by the crust or ring formation mainly of sulfur (or crude). For this purpose, various balances based on the different compounds entering the kiln or forming within it were made, taking sulfur as the main substance of study, in order to determine several aspects, such as: its influence in ring formation, the amount in the system, its main reactions and how to alleviate or control their incorporation, under regular operating conditions and under instable conditions. With the use of Microsoft Excel the corresponding balances for various reactions involved in the behavior of sulfur in the kiln were carried out, which showed that sulfur should be handled close to the parameters established for proper operation of the kiln and to avoid unnecessary stops by forming rings which incur huge economic costs.

Keywords : Ring; Sulfur; Kiln; Microsoft Excel; Reactions.
