Study of the flameless combustión mode in presence of the thermal load fluctuation
The present study evaluated numerically and experimentally in a 20 kW furnace (using natural gas as fuel and with an equivalent ratio of 1.2) the stability of the flameless combustion regime due to the fluctuation of the thermal load through the use of different air flow (43 scfm, 63 scfm y 83 scfm)...

description |
The present study evaluated numerically and experimentally in a 20 kW furnace (using natural gas as fuel and with an equivalent ratio of 1.2) the stability of the flameless combustion regime due to the fluctuation of the thermal load through the use of different air flow (43 scfm, 63 scfm y 83 scfm) and an Air-Helium mixture (Air 82.02 scfm and Helium 7.06 scfm); the last one it was used to evaluate the behavior of the system in the face of an increase in the load fluid specific heat capacity. The study was divided in two parts, numerical simulation and experimental phase. From the numerical simulation was calculated the temperature profile, CO profile, the recycle ratio Kv and the mass of flue gases recirculated. In the experimental phase the temperature profiles obtained showed a decrease in the temperature of the combustion chamber as the load air flow increased however, this decrease did not affect the thermal uniformity inside of the furnace. Furthermore the useful efficiency showed an increase when went over from a load air of 43 scfm to 63 scfm, followed by a decrease of it with the other load flows. |

El estudio se dividió en dos partes, una parte numérica y otra experimental. A partir de la simulación numérica se calculó el perfil de temperatura, el perfil de CO, el factor de recirculación Kv y la masa de productos de combustión recirculados. En la fase experimental los perfiles de temperatura mostraron una disminución en la temperatura de la cámara de combustión a medida que el flujo de aire de carga incrementaba, sin embargo, esta disminución no afectó la uniformidad térmica dentro del horno. Además, la eficiencia útil mostró un incremento al pasar de un flujo de aire de carga de 43 scfm a 63 scfm, seguido de una disminución al incrementar la carga térmica.application/pdfspaUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/4433Copyright (c) 2017 Juan David Echavarría, Andrés Adolfo Amell ArrietaAttribution 4.0 International (CC BY 4.0)http://creativecommons.org/licenses/by/4.0Acceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia; Vol 13 No 25 (2017); 185-208Ingeniería y Ciencia; Vol 13 No 25 (2017); 185-208Study of the flameless combustión mode in presence of the thermal load fluctuationEstudio del régimen de combustión sin llama ante la variación de la carga térmicainfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionarticlepublishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Flameless combustionRecirculation factorTemperature profileThermal uniformity factorNO emissionsIngenieríaEnergyCombustión sin llamaFactor de recirculaciónPerfil de temperaturaFactor de uniformidad térmicaEmisiones de NOEchavarría, Juan DAmell Arrieta, AndrésPrograma de Sostenibilidad 2016-2017 grupo GASURE, de la Vicerrectoria de Investigación de la Universidad de AntioquiaColcienciaIngeniería y Ciencia1325185208ing.ciencORIGINAL8.pdf8.pdfTexto completo PDFapplication/pdf1422242https://repository.eafit.edu.co/bitstreams/7c4e272e-d6f1-4435-90fc-561dddbeca38/downloaddbe93c992d9d00bc0ec7ca5f91f2781bMD52articulo.htmlarticulo.htmlTexto completo HTMLtext/html374https://repository.eafit.edu.co/bitstreams/c89e9c61-01ed-4cf1-9d2f-dcee3416e918/download169dd9d167254bdc3f59b9f6601ff229MD53THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/0771a712-d325-4053-9ce0-982c86d039b2/downloadda9b21a5c7e00c7f1127cef8e97035e0MD5110784/13176oai:repository.eafit.edu.co:10784/131762020-03-01 17:45:27.828http://creativecommons.org/licenses/by/4.0Copyright (c) 2017 Juan David Echavarría, Andrés Adolfo Amell Arrietaopen.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co |
