Within the framework of the AVIATOR project (Assessing
Impact of aviation emissions on local air quality at airports:
TOwards Regulation), two experimental campaigns were carried out at Adolfo Suárez Madrid-Barajas airport
at the Adolfo Suárez Madrid-Barajas airport, northeast of Madrid
located northeast of Madrid (Spain). The experimental equi...
A high fidelity air quality measurement system consisting of a Baseline System including on-line (TSI SMPS) and off-line measurement devices (high volume PM10 sampler and low pressure Berner type impactor (BLPI)) was placed between the two runways of Madrid-Barajas airport. Metallic elements were determined in the collected filters and substrates b...
Differential Mobility Analyzers (DMA) have been studied for decades to classify a wide range of particle sizes. Its correct behavior is determined by the resolution, influenced by Brownian diffusion losses, distortions in the electric and flow field. The design configuration, especially inlets and outlets, can be a reason of these effects, affectin...
AVIATOR Project is divided into the following three main pillars:
- The first pillar is related to the experimental measurement campaigns which will be carried out across the project in order to assess and standardize the measurement systems of aircraft engine emissions. This block contains WPs 2, 3 & 4,
- The second pillar includes the WPs 5 & 6...
Emissions from aircraft engines have adverse effects on air quality in and around airports, contributing to health concerns within neighboring communities. To improve airport local air quality (LAQ) assessment, further understanding and determination of Total Particulate Matter (TPM) within aircraft engine exhaust plumes is required. This study, su...
“AVIATOR Project: UFP size distribution characteristics from in-stack measurements of evolving aircraft engine exhaust at INTA”:
The objective of this study is the evaluation of the particle size emitted by a large aircraft engine. In this investigation, the UFP size distribution has been assessed with two devices that use different technologies fo...
COMBINING NON-INTRUSIVE AND EXTRACTIVE METHODOLOGIES FOR
SOOT DETERMINATION ON AIRCRAFT ENGINE EMISSIONS
A feasible alternative for agricultural or forestry waste management is the operation of a distributed network of sustainable Medium Combustion Plants (MCPs). However, one of the main factors that hinder its development is the propensity to operational problems derived from corrosion, slagging and fouling characteristics of both bottom and fly ashe...
A miniaturized analytical procedure to determine selected polycyclic aromatic compounds (PACs) in low mass loadings (<10 mg) of particulate matter (PM) is evaluated. The proposed method is based on a simple sonication/agitation method using small amounts of solvent for extraction. The use of a reduced sample size of particulate matter is often limi...
The aim of this work was to optimize and evaluate an analytical procedure to determine selected polycyclic aromatic hydrocarbons (PAHs) using real samples. Samples of ash were collected during biomass combustion tests under different operating conditions during one week. PAHs were quantified using liquid chromatography with fluorescence detection....
Control of particulate matter emissions by means of hybrid filter has been included in the experimental plan of a research project in the field of Mediterranean agro-forestry waste biomass combustion at medium scale. Application of hybrid filters to biomass combustion has not been thoroughly experimented so far. An identification of the most import...
A simple analytical method using low volumes of solvent for determining selected PAHs and NPAHs in PM samples is presented. The proposed extraction method was compared with pressurized fluid (PFE) and microwave (MC) extraction techniques and intermediate precision associated to analytical measurements were estimated. Extraction by agitation with 8...
As aircraft traffic grows and other combustion sources become cleaner, the potential importance of aircraft related emissions increases in relation to both health and environmental effects. There is currently minimal data available to provide speciation profiles of polynuclear aromatic hydrocarbons (PAH) for local air quality analysis purposes. INT...
As the aviation sector continues to grow into the future, there is concern about atmospheric and Local Air Quality (LAQ) particle emissions and their impact on the environment and on human health (Waitz, 2004). Within this study, a series of particulate emissions experiments were carried out on different turbofan engines at INTA Turbojet Test Centr...
The determination of polycyclic aromatic compounds (PACs) in aerosols is still an attractive target for analytical purposes. However, the analysis is complicated for samples with very low mass loading, for which the sample preparation often involve a large consume of time and solvent, with a high risk of loss of analytes. It is necessary to stress...
This work demonstrates the feasibility of a robust and effective control of the emissions of particulate matter and heavy metals from olive tree pruning combustion, as well as from its blends with two customary local components (a composted fraction of sewage sludge and a fraction of municipal solid waste with a high plastic content), in an approxi...
Present work shows the results of a study on emission of particulate matter (PM) during a series of tests carried out in the Turbojet Engine Test Centre of INTA. Engines are subjected to different operation cycles in which the power delivered by the engine was varied. The measurements were performed in the facility stack.
Se presenta una descripción técnica pormenorizada de cada uno de los elementos que una instalación que constituye un Banco de motores estacionarios para estudio de emisiones ha integrado y cuya capacidad abarca a estudios de los efectos del motor, combustible, condiciones de operación, y metodología de muestreo y medida sobre las emisiones (gases y...
El desarrollo de materiales filtrantes cerámicos catalíticos, orientados a la reducción catalítica selectiva de óxidos de nitrógeno, capaces de operar a temperaturas suficientemente altas permiten obtener rendimientos de reacción superiores al 90%. Por otra parte, la absorción en seco de gases ácidos, como dióxido de azufre o cloruro de hidrógeno,...
En este trabajo, se presentan algunos resultados previos para la valoración de emisiones en un motor diesel con una potencia máxima de 97 kW, funcionando sin carga a 600 r.p.m, utilizando como combustible mezclas de biodiesel y gasóleo en diferentes proporciones. El estudio se ha desarrollado dentro del proyecto “Evaluación de Emisiones de Biodiese...
