Lab-scale prototypes of adaptive façade panels for experimental validation Control algorithms to optimize solar energy harvesting and storage Thermosiphon vertical integration into façades

One reason for heat losses in buildings is inadequate insulation. Vacuum Insulation Panels (VIPs) is emerging as a promising solution, being more energy efficient than conventional insulation materials, thinner and lighter. A VIP is made by placing a core insulation material inside a gas-barrier envelope and evacuating the air from inside the panel...

The use of a waste-based secondary fuel in clinker kilns is a widely used practice. Nevertheless, specific studies to understand the destruction mechanism of exhaust pollutants in cement raw material (CRM) are limited. This work focuses on the possible catalytic effect of the interaction of exhaust gases from the com-bustion of sewage sludge with v...

Emission factors of carbon oxides, light hydrocarbons, polycyclic aromatic hydrocarbons (PAHs), polychlorodibenzodioxin/furans (PCDD/Fs), and dioxin-like polychlorinated biphenyls (PCBs) were determined in the combustion of a mixture of pine needles and cones in a residential stove. Furthermore, several combustion experiments were carried out in a...

The influence of iron nanoparticles in the fuel-rich combustion of PVC has been studied in this work. Dynamic runs for PVC and the mixture PVC and iron nanoparticles were firstly carried out by TGA-MS in order to study the influence of iron on the compounds evolved in the thermal degradation of PVC. To complete the study both PVC and a mixture of P...

In an initial effort to minimize some of the uncertainty regarding the open burning of biomass, emission factors of carbon oxides, light hydrocarbons, PAHs, PCDD/Fs and dioxin-like PCBs were determined in the combustion of tomato plant in a residential stove and in two runs at 500 degrees C and 850 degrees C in a laboratory scale reactor. In all th...

A kinetic study of the thermal decomposition of tomato plant has been carried out under different conditions by TG and TG–MS. A total of 24 experiments were performed in a nitrogen atmosphere (pyrolysis runs) and also in an oxidative atmosphere with two different oxygen concentrations (10% and 20% oxygen in nitrogen). Dynamic runs and dynamic+isoth...

Bag filter (BF) fly ash from a hazardous waste incinerator located in Medellín, Colombia was characterized. Particle size distribution, chemical composition, metal loading, surface area, morphology, and chemical environment were assessed before and after fly ash extraction with toluene. Fly ash consists of low surface area platelets of SiO(2) small...

Dioxin and furans (PCDD/Fs) are released into the environment from many possible sources, including incineration, industrial processes, and internal combustion engines. The PCDD/Fs have been identified as agents responsible for many toxic responses in exposed individuals, including cancer and developmental/reproductive dysfunctions. Because of thei...

The decreasing costs and increasing availability of electronic products of all kinds, including mobile phones, audio and video equipment, and personal computers and their accessories, coupled with advances in technology that rapidly make these products obsolete, foretell a growing disposal problem.The materials employed in the present work were a m...

A comparison between different emission rates of various pollutants obtained from various wastes is presented. The studied wastes were the following: polyethylene (PE), tyres, sewage sludges, polyvinyl chloride (PVC), cotton textiles, polyester textiles, meat and bone meals (MBMs), varnish wastes, olive oil solid waste (pomace), waste lube oils and...

Paper recycling is an environmental important activity that is carried out in all the countries, but during the recycling process a paper waste is produced. Generally these wastes are placed in landfill sites but it is possible to profit it as secondary fuel and raw material in manufacture furnaces. In this work the combustion of the waste papers w...

In this work, an analysis of the emission of different pollutants when replacing partially the fuel type used in a cement kiln is done. The wastes used to feed the kiln were tyres and two types of sewage sludge. The increasing mass flow of sludge is between 700 kg h(-1) and 5,500 kg h(-1)1, for a total production of clinker of 150th(-1), whereas th...

Nowadays the use of waste as secondary fuel in clinker kilns is an extensive practice, but the interaction between cement raw material (CRM) and the combustion gases of the fuels has not been extensively studied. Because of that, in this work the effect of the interaction of exhaust from the combustion of sewage sludge and CRM has been studied in a...
