In this paper, the technical, financial and legal feasibility of employing solar cogeneration for the food industry sector in Peru will be demonstrated. In consequence, we will quantify the electric and thermal energy obtained from a conventional Rankine cycle, with the particularity that the water used to condense the steam that exits the turbine will be employed for the required processes in the industrial plants, because of the high temperature obtained from the heat exchange with the steam. In addition, we will detail the processes in which the obtained energy will be employed, the quantity of devices to be used in this system, as well as the required specifications and the thermodynamic parameters, for a proper operation of the cogeneration system. Moreover, we will prove the legal feasibility of choosing a solar cogeneration system in the Peruvian legal system, and, in ...

In the present study, the control of the pyrolysis temperature was carried out in a gasification process of eucalyptus wood, its prediction is made based on the operating parameters of the reactor to ensure the obtaining of a synthesis gas with the required quality. The results obtained from the mathematical modeling for the prediction of the pyrolysis temperature with the use of artificial intelligence techniques and the development of artificial neural networks are shown, with experimental data of the process. For this reason, an experimental statistical design of type 3n was implemented, with two additional replications, by means of which the training of an artificial neural network capable of predicting the pyrolysis temperature in a downdraft type gasifier with cogeneration was carried out. The prediction of the pyrolysis temperature has an error of 4.6 oC and an adjustment of 93.71...

The research results obtained on the effect that occurs on the properties of the synthesis gas obtained as a result of a biomass downdraft gasification process is presents in this paper, working with a cogeneration system internal to the reactor. A study of the previous related works was carried out, from which the dependent and independent variables necessary to evaluate the final quality of the process in the presence and absence of cogeneration were determined. For this, an experimental statistical design of four levels of type 4n was implemented, which allowed the performance of a comparative statistical analysis of the working states of the gasifier. On the other hand, an energy and exergy analysis of both states is presented where the potential of the gasification process to reuse thermal energy can be verified by incorporating a cogeneration system.

In this work, an energetic evaluation of appropriate mixture of cane harvest waste / sugarcane bagasse was carried out to improve the cogeneration capacity of both electricity and steam for the sugar production process in a typical Peruvian sugar industry. Peru has a tradition in the sugar industry characterized by its high sugarcane plantation productivity; However, the problem that persists to the present is the poor form of cane harvest (pre-burned cane in the field) and obsolescence technology used in cogeneration process. The methodology begins with the mechanized harvesting in pilot area of cane plantation, followed by preparation and drying processes of harvest residues. Samples of waste are taken to laboratory for physicochemical and energetic characterization at different moisture conditions, obtaining calorific value and elemental content values. The appropriate waste / b...

Mediante la investigación que da origen a este artículo se busca demostrar la viabilidad técnica, financiera y legal del uso de la cogeneración solar para el sector de industrias alimentarias en nuestro país; para esto se procederá con una cuantificación de la energía eléctrica y térmica obtenida mediante un ciclo Rankine convencional, con la particularidad de que el agua usada para condensar el vapor saliente de la turbina será utilizada para los procesos requeridos en las plantas industriales, debido a la elevada temperatura obtenida del intercambio térmico con el vapor. Todo ello se realizará detallando los procesos en los que se aprovechará la energía obtenida y la cantidad de equipos a utilizar en este sistema, así como las especificaciones necesarias y parámetros termodinámicos para el correcto funcionamiento del sistema de cogeneración. Además, demos...

El Planeamiento Estratégico de la Industria Peruana de Cerámicos se elaboró con el propósito de proyectar a la industria al futuro para que alcance un crecimiento sostenido al año 2028. Fue elaborado en función al Modelo Secuencial del Proceso Estratégico, propuesto por D’Alessio (2015), que involucra analizar detalladamente la situación actual de la industria a nivel global, regional y local, y en base a ello, proponer una misión, visión, valores y código de ética. Asimismo, mediante un análisis de factores externos e internos de la industria se identificaron sus oportunidades, amenazas, fortalezas y debilidades, que permitieron establecer los intereses organizacionales y los objetivos de largo plazo, y a partir de ello plantear estrategias que permitan alcanzar la visión planteada. Se determinaron cinco objetivos de largo plazo que buscan: (a) incrementar las exportacio...

The study focuses on the design of the MK3 kiln as an eco-friendly solution to mitigate the pollution of (PM2.5 and PM10) generated by artisanal brick kilns. The MK3 kiln consists of three chambers constructed with construction and demolition waste (CDW), interconnected by lower ducts that aid in the continuous flow of heat and filter pollutants. Each kiln has a 5 cm opening in the dome to accommodate a copper industrial torch with a power of 1080 BTU/h, equivalent to 0.32 kW. Additionally, a 220V axial fan is installed in the chimney to supply the necessary air to the kilns through upper ducts, allowing complete combustion during the brick baking process. As a result, PM2.5 was measured at a quantity of 23 μg/m 3 , and PM10 emissions at 90 μg/m 3 , both of which do not exceed Environmental Quality Standards (ECA). Regarding the brick baking process, heat is recovered from the "combust...
