Computational model of a Calcium-looping fluidized bed calcination reactor with...
Rodrigues, Diogo; Rivero, Mayra Alvarez; Pinheiro, Carla I.C.; Cardoso, João P.; Mendes, Luís FilipeABSTRACT: The Calcium-looping process is a promising option for thermochemical energy storage in concentrating solar power plants. A crucial element of this process is the solar calcination reactor, where the endothermic reaction of CaCO3 calcination occurs with formation of CaO and CO2. The solar energy that is chemically stored in the reaction products can be retrieved by the exothermic reaction of CaO carbon...

Rivero, Mayra Alvarez; Rodrigues, Diogo; Pinheiro, Carla I.C.; Cardoso, João P.; Mendes, Luís FilipeABSTRACT: The calcium looping process, based on the reversible calcination-carbonation reaction cycle of CaCO3-CaO, is an emerging and promising technology for thermochemical energy storage in concentrating solar power plants. In this process, concentrated solar energy is used to carry out the endothermic solar-driven calcination of CaCO3 with formation of CaO and CO2 as products in a solid-gas reactor. In this...

Rivero, Mayra Alvarez; Rodrigues, Diogo; Pinheiro, Carla I.C.; Cardoso, João P.; Mendes, Luís FilipeABSTRACT: A new unidimensional computational model is developed to simulate a calcination reactor in a Calcium-looping process for thermochemical energy storage in concentrating solar power systems. The proposed reactor is an absorber tube exposed to concentrated solar radiation. This tube is also the riser of a circulating fluidised bed where the calcination reaction takes place. The proposed heat transfer pro...

Cardoso, João P.; Mendes, Luís Filipe; Mendes, J. FarinhaABSTRACT: The development of new receivers for central receiver systems operating at high temperatures require the development of suitable tools able to accurately simulate heat and mass transfer processes. Such tools should be able to process complex receiver geometries with nongray and directionally nonideal surfaces. This work introduces the development of a new tool, HeatTracer, for the simulation of radiat...

Pre-heating boiler feedwater for expanded cork agglomerate production using a p...
Castro, António; Cardoso, João P.; Mendes, Luís Filipe; Azevedo, Pedro; Mendes, J. FarinhaABSTRACT: The production of expanded cork agglomerate involves significant heat demand, requiring superheated steam at temperatures ranging from 300°C to 370°C. The energy required to this process can be suitably provided by concentrating solar thermal collectors. This work considers the thermal energy needs of a real plant, presenting the technical and economical analysis performed for a solar heat for industr...
Postmodern City, Gentrification and the Social Production of Fragmented Space
Mendes, Luís FilipeA new type of city has undoubtedly been taking shape in the latest decades to which, by commodity and lack of a better expression, is given the name of ‘postmodern city’. The compact city, with sealed social zoning and precise limits, whose centre shows a relative social homogeneity, is torn in a group of distinct fragments where the effects of cohesion, continuity and urban readability give way to more complex...
