Optimización de la matriz energética del horno continuo de cocción B&T 3200 en la Empresa C.A. Ecuatoriana de Cerámica.

Abstract

The objective of this study is the optimization of the B&T 3200 baking oven in the company C.A. Ecuadorian Ceramics through the use of its alternative fuel system with Natural Gas through technical and environmental analysis. A complete energy balance was made in the oven cooking zone working with diesel to determine the change of the energy matrix from diesel to natural gas. It is determined that the total heat contributed by combustion is 3136.6 kW, of which 65.52% is delivered to remove the free water from the biscuit, 21.20% for all reactions to occur, and 13.28% of heat lost by walls and leaks. Once the necessary heat is known and considering the seasonal conditions of the kiln, diesel consumption is calculated, resulting in 2153.00 kg / s and natural gas consumption of 1922.00 kg / s. Subsequently, the greenhouse gas emissions generated by combustion are analyzed, resulting in diesel emitting 7219.79 kg of CO2 / s and natural gas 5998.40 kg CO2 / s. For the mass flows obtained from diesel and natural gas, there is a cost of 1837.87 USD / s and 679.089 USD / s, respectively. The production cost per m2 in the cooking stage when using natural gas as a fuel to generate thermal energy is lower compared to the price when using diesel. Therefore, the use of natural gas optimizes the cooking process by decreasing the production cost, CO2 emissions, and fuel consumption.
