Use of thermal energy and analysis of barriers to the implementation of thermal efficiency measures in cement production: Exploratory study in Colombia

摘要: Abstract The cement industry is one of the world’s largest energy consumers. In this work, a walk-through study representative companies was carried out to characterize profile in Colombia, with emphasis on evaluating degree obsolescence technology used processes, as well identifying main barriers that prevent adaptation more efficient technologies. Perception-surveys were performed among managers determine hinder implementation efficiency measures. A factor quantifies influence each type barrier defined according results survey. show Colombian has specific consumption competitive producers world, while technological found at medium - low level. Furthermore, penetration technologies and measures identified hidden costs associated these Finally, some conventional emerging are proposed improve thermal use processes studied.
