Article
Full-text available
Energy production by solid biofuel combustion is the most commonly used biomass-to-energy technology. Nevertheless, the ash generated from the combustion process leads to problematic phenomena. Depending on the origin and chemical characteristics of the biomass used, the combustion technology and conditions, and the melting temperature of the ash,...
Article
Thermogravimetric curves in air, measured for the different types of agricultural residues from olive trees (leaves, pruning and wood) at different heating rates (5, 10, 20, 40, 100 K/min), are subjected to kinetic evaluation by model-based and model-free methods. It is shown that the combustion process in the samples analyzed can be divided into t...

Esta guía pretende ser un documento de consulta para las administraciones locales que facilite el cumplimiento de sus competencias en la gestión de residuos. En ella se pretende determinar, definir y concretar el marco legislativo y administrativo de los Entes Locales en esta materia, con la finalidad de establecer sus competencias y la forma de ge...
Article
In the Mediterranean areas of southwest Europe, olive tree pruning residues generate substantial amounts of residual biomass. Pelleting this biomass supposes the conversion of a residue difficult to manage into an energy resource especially indicated to be used in the areas where these groves exist. The final quality of pellets varies depending on...
Conference Paper
Full-text available
Building envelopes are the part of the buildings most exposed to the inclement weather and thus have significant impact on the energy performance as a consequence of higher thermal transfers produced. Therefore, new solutions for building envelopes are required as a way to save energy in residential buildings. In this regard, the European Directive...
Article
Full-text available
The thermal conversion of rice straw is an attractive option for recovering its energy, but the process requires exhaustive control because of ash-related problems. Straw washing is one method of reducing ash-related problems and improving combustion behaviour. In this study, the ash of washed and unwashed rice straw samples was chemically characte...
Article
Full-text available
The building sector is one of the main bodies responsible for primary energy consumption in Europe. Consequently, energy certification of buildings is being promoted under the policy to monitor and reduce energy consumption. By means of the European Directive 2002/91/EC on the Energy Performance of Buildings (EPBD), and the recast in the Directive...
Article
The rise in energy consumption has made the use of alternative fuels a priority. Residual biomass is an abundant renewable energy resource whose use can lead to significant socioeconomic and environmental benefits. This biomass is destined to play an important role in the new energy model since agricultural residues are produced in huge amounts thr...
Article
Rice straw can be used as a renewable fuel for heat and power generation. It is a viable mean of replacing fossil fuels and preventing pollution caused by open burning, especially in the areas where this residual biomass is generated. Nevertheless, the thermal conversion of rice straw can cause some operating problems such as slag formation, which...
Article
The heterogeneity of biomass makes it difficult if not impossible to make sweeping generalizations concerning thermochemical treatment systems and the optimal equipment to be used in them. Chemical differences in the structural components of the biomass (cellulose, hemicellulose, and lignin) have a direct impact on its chemical reactivity. The aim...
Article
Urban surfaces receive waste deposits from natural and human sources, which create a negative visual impact and are identified as potentially significant contributors to water and air pollution. Local councils are usually responsible for the sweep of roads and footpaths to keep the environment clean and free of litter. Quality controls are useful i...
Article
As fossil fuels are not only a limited resource, but also contribute to global warming, a transition towards a more sustainable energy supply is urgently needed. Therefore, today's environmental policies are largely devoted to fostering the development and implementation of renewable energy technologies. One important aspect of this transition is t...
Article
The quality of pellets is directly related to their physical, chemical, and mechanical properties. It affects the emissions resulting from their combustion and also their use in stoves and boilers. Certain European countries have developed standards specifying control parameters and guidelines with a view to guaranteeing the effective and environme...
Article
Biomass is an abundant renewable energy source; however, because of its characteristics it is not easily used in its original form. Pelletization technology represents mass and energy densification that provides easier biomass fuel handling and feeding. A privately owned pelletization industrial plant has been set up to produce pellets from agricul...
