Desarrollo de una herramienta informática para aplicación en balances de masa y energía en el horno rotativo de la Planta Guapán-UCEM

Abstract

The objective of this work is to promoteto the technical personal of the area of Production of the plant of cement Guapán of the “Unión Cementera Nacional”, the realization of periodic or permanent balances of mass and energy on the Pre-heater-kiln – cooler system, counting with the help of an informatics tool that has been developed in Matlab to make the calculus easier and the obtaining of results for the heat balances, that should always be done on the kiln-reactor of clinker to evaluate its performance and operative efficiency. First, it’s described the conceptual theoretical framework of the process of kiln production manufacturing, base component of the kiln, and then the methodology to follow to take the measurements, obtaining the field data and central control of the variables and operation parameters of the pre-heater-rotative kiln-cooler system and finally it is explained how to make the calculus and the obtained results with the help of the developed informatics tool. This work attempts to detail simply and understandable the inflows and outflows of mass and energy that exist in the rotative kiln system, it is applied a standard notation that the operative personal of the plant Guapán can apply for the register and the comprehension of every input and output that intervene in the practical realization of the energy balance and also explains how to calculate the determination of not known variables. Once determinated how to obtain the data and calculus, which they are going to be submitted, we proceeded to develop an informatics tool, in which the inputs are introduced for the program to make the calculus, this program also counts with a function that allows to make a Sankey graphic, that resumes and interprets the results of the balance, as well as the program is able to store the results obtained as many times as the balance is done and those will be a reference base and a historical tendency of the energetic efficiency with which the plant has operated. When the balance is over, the necessary observations should be registered with respect to the interpretation of results, to establish the pertinent recommendations and try the continuous improve in the installations and the optimal way to operate the system to get the final purpose of improving the productive yield of the kiln and to have a more efficient use of thermal energy that the process consumes, this is to say, to produce as much clinker with the lowest consume of fuel, measured in kcal of fuel per kg of clinker produced.
