Development of a reduced-order model of an industrial billet heating furnace
Alvarez, Frederico; Costa, Sérgio; Santos, Daniel; Canhoto, Paulo; Malico, Isabel; Rato, Luís; Gonçalves, Teresa; Barão, Miguel; Lima, Rui PedroThis work is part of the ongoing efforts under the Audit Furnace project to develop a reduced-order model (ROM) that allows for fast analysis of combustion, fluid flow and heat transfer processes that occur inside industrial furnaces. A billet heating furnace is considered here, which uses propane as fuel and processes circa 5000 kg of material per hour with a billet temperature set point at the exit of 745 ºC....
Modelling and optimization of the thermal equipment network of an industrial au...
Alvarez, Frederico; Canhoto, Paulo; Malico, Isabel; Lima, Rui PedroThe energy-intensive industry is an important player in the quest to meet the ambitious plans of the European Union to reduce the consumption of fossil fuels and, consequently, the emission of greenhouse gases, mainly CO2. In that sense, energy efficiency in thermal processes in industry becomes a key point to achieve those goals. Another important measure to achieve CO2 reduction targets is the use of green hy...
Development of a model for the promotion of energy efficiency in an automotive ...
Malico, Isabel; Zdanowsky, Francisco; Pécurto, Flávio; Alvarez, Frederico; Canhoto, Paulo; Lima, Rui PedroThe automotive industry faces technological challenges to improve its sustainability under the pressure of economic and environmental requirements. One of the most cost-effective ways of reducing energy costs is through the implementation of energy efficiency measures. Typically, paint-shops include the most energy intensive processes in a vehicle assembly plant (Fig. 1). They consume both electricity and fuels...
Simulation of the thermal equipment associated with a paint-shop oven of a vehi...
Zdanowski, Francisco; Alvarez, Frederico; Gonçalves, João; Pécurto, Flávio; Malico, Isabel; Canhoto, Paulo; Lima, Rui PedroThe automotive industry is characterized by complex and energy-intensive processes, which consume a significant amount of electricity and fuels. Therefore, improving the energy efficiency and promoting the use of renewable energies in this industry is of the highest importance. Among the different sectors, typically, in vehicle assembly plants, paint-shops are the most energy intensive consumers, requiring larg...
A grey-box Neural Network Composite Model for an Industrial Heating Furnace
Santos, Daniel; Costa, Sérgio; Rato, Luís; Gonçalves, Teresa; Malico, Isabel; Canhoto, Paulo; Alvarez, Frederico; Barão, MiguelIndustrial furnaces consume large amounts of energy and their operating points have a major influence on the quality of the final product. Design- ing a tool that analyzes the combustion process, fluid mechanics and heat transfer and assists the energy audit work is then of the most importance. This work proposes a hybrid composite model for such a tool, having, as its base, two white-box models, namely a detai...
