Optimización del proceso de combustión en el área de clinkerización mediante la utilización de analizador de gases en la Empresa Cemento Chimborazo C.A.

Abstract

The optimization of the combustion process in the clinkerization area through the use of a gas analyzer in the company Cemento Chimborazo C.A., promises an economic and productive benefit. The analytical method was applied, to know the state of the raw material, through the determination of: lime saturation and modules, in the laboratory. The TESTO 350 portable gas analyzer was used during four months of study, more frequently in September and October 2012 when the fixed analyzer was not installed; for which a previous study of the same was necessary. The monitoring was carried out in the exhaust gas suction duct of the furnace. Once the fixed analyzer ITECA SOCADEI was installed and started up at the furnace entrance in November 2012, the data recorded by the analyzer was taken, and at the same time the portable gas analyzer was used in December 2012 and January 2013 to compare the data and calculate the air infiltration in the preheating tower. Once the calculations were made and with the use of the analyzers, the results are as follows: Initial Diagnosis: CO: 1.14%; O2: 3.58%; NOX: 0.017%; kcal/kg Ck: 1055.86; gal/Tm Ck: 31.15. Final Conditions: CO: 0.386%; O2: 2.246%; NOX: 0.052%; kcal/kg Ck: 957.35; gal/Tm Ck: 28.246. I conclude that fuel consumption per ton of clinker and gaseous emissions were reduced, thanks to the use of the aforementioned analyzers. It is recommended that the company stay within the established parameters to achieve an even greater improvement in the process through the use of alternative fuels.
