Book excerpt: CE TRAVAIL EST DESTINE A UNE MEILLEURE COMPREHENSION DES PHENOMENES PHYSIQUES ET CHIMIQUES A L'ORIGINE DE LA REDUCTION DES OXYDES D'AZOTE LORS DE LA COMBUSTION EN AIR HUMIDE. UNE SYNTHESE BIBLIOGRAPHIQUE SUR DES SUJETS CONNEXES FAIT APPARAITRE UN MANQUE DE DONNEES EXPERIMENTALES LOCALES NECESSAIRES A UNE ANALYSE FINE DU ROLE DE L'EAU DANS LA COMBUSTION DU GAZ NATUREL. NOUS AVONS DONC DEVELOPPE UN BRULEUR DE LABORATOIRE PRODUISANT UNE FLAMME METHANE / AIR NON PREMELANGEE A SWIRL, CONFINEE, DANS LAQUELLE DIFFERENTS DEBITS DE VAPEUR D'EAU SONT INJECTES (JUSQU'A 1,7 MOLE / MOLE DE COMBUSTIBLE). LES TECHNIQUES DE MESURES UTILISEES SUR CETTE FLAMME SONT L'ANEMOMETRIE DOPPLER LASER, LA MESURE DE TEMPERATURE PAR MICROTHERMOCOUPLES, ET L'ANALYSE LOCALE DES GAZ (CO, CO 2, O 2, C NH M, NOX). DES VISUALISATIONS DE LA FLAMME PAR FLUORESCENCE (SPONTANEE ET INDUITE PAR LASER) DU RADICAL OH SONT AUSSI EFFECTUEES. L'ANALYSE DES MESURES LOCALES MONTRE QUE L'INJECTION D'EAU NE MODIFIE LA STRUCTURE AERODYNAMIQUE DE LA FLAMME QUE DANS LES PROPORTIONS DES DEBITS VOLUMIQUES DE DILUANTS INJECTES, LES TEMPERATURES MAXIMALES AU NIVEAU DE LA ZONE DE RECIRCULATION CENTRALE DIMINUENT DE 200 A 300 K. UNE SIMULATION NUMERIQUE DU BRULEUR A ETE EFFECTUEE AU MOYEN DU LOGICIEL FLUENT, LA TURBULENCE ETANT MODELISEE PAR LE MODELE K- ET LA COMBUSTION PAR UN MODELE SIMPLIFIE A CINQ REACTIONS. ELLE PERMET DE RETROUVER LES TENDANCES DU COMPORTEMENT DU BRULEUR. L'ASPECT CHIMIQUE DE L'EAU EST ETUDIE PAR COMPARAISON AVEC UNE DILUTION A L'ARGON. LA SIMILITUDE DES COMPORTEMENTS LOCAUX, Y COMPRIS DE LA REDUCTION DES NOX, INDIQUE UNE FORTE PREDOMINANCE DE L'EFFET PHYSIQUE, PLUTOT QUE CHIMIQUE, DE L'EAU SUR LA PRODUCTION DES NOX. CET EFFET EST CONFIRME PAR UNE SIMULATION EFFECTUEE A L'AIDE DU CODE CHEMKIN II, EN UTILISANT LE SCHEMA CINETIQUE GRI 2.11. TOUTEFOIS LES IMAGES DE FLUORESCENCE DU RADICAL OH, CORRIGEES DU QUENCHING, METTENT EN EVIDENCE UNE CONCENTRATION DE OH PLUS ELEVEE DANS LE CAS DE LA DILUTION PAR L'EAU.

Available in PDF, EPUB and Kindle. Book excerpt: Si l'eau a été utilisée comme additif pour améliorer la combustion, la puissance des machines, voire comme antidétonant puis, plus récemment, comme élément réduisant la formation des oxydes d'azote, la combustion humide offre la perspectives de performances énergétiques et écologiques remarquables, notamment dans le cas des turbines à combustion terrestres et des générateurs thermiques visant la récupération de la chaleur latente associée à la condensation de la vapeur d'eau des gaz de combustion.En combustion humide, trois fluides pénètrent dans la chambre de combustion : le combustible, l'air de combustion et l'eau additionnelle.Pour analyser ces procédés, une méthode dite Diagramme Hygrométrique de Combustion, a été développée. Cette méthode, est notamment à recommander pour l'établissement des rendements de combustion, le dimensionnement des échangeurs biphasiques. Des informations sur les modifications des conditions de la combustion sont également fournies.

Download or read book Environment in Key Words written by Isaac Paenson and published by Elsevier. This book was released on 2016-06-28 with total page 978 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems ignore international boundaries. Toxic wastes travel by water and air, sometimes displacing the effects of an environmental disaster entirely outside of its country of origin. It is now understood that to overcome the problems that face us international co-operation is required. This important work is designed to assist in that process, by helping to break down the language barriers that stand between countries. The manual, written in parallel English, German, French and Russian texts, provides the basic tools of communication in the specialized fields of environmental sciences between speakers of these languages. Each chapter has been revised in each separate language by specialists in the field to guarantee the authenticity of the information presented. The author is unique in his approach, presenting the key-words in context, as opposed to simple glossary entries, allowing the reader to fully understand the complex relations between the word and the concepts involved. A comprehensive index written in all four languages guides the reader through the text, providing references to the words as they are used in different disciplines.
