| Resumo: | In the pursuit of more sustainable urban energy systems, recovering industrial waste heat presents a promising opportunity to enhance energy efficiency and reduce emissions. This thesis explores the technical and economic feasibility of capturing excess heat from an industrial process and repurposing it to supply a new low-temperature district heating network planned for a new residential district. By identifying suitable heat recovery points in the industrial process and estimating the available thermal energy under normal operating conditions, it is possible to approximate the power that can be extracted. Based on the projected heat demand of the residential area and relevant building regulations, a design of the distribution network is developed to align the supply with demand. In addition, the integration of complementary technologies is considered to further improve heat recovery. A financial analysis is also conducted to assess the investment requirements, operational costs, and expected revenues from heat delivery, under a model of industrial-urban cooperation. Recovering residual heat from an industrial activity increases the overall efficiency of the production system, as well as reducing the need for additional energy for heating. All this contributes to the achievement of longterm sustainability. As urban development is increasingly taking place near existing industrial zones, this type of integration creates opportunities for these kinds of projects. |
