Eco fogón Mejorado Modelo Justa, utilizado para reducir el consumo de Leña.

2.2 Detailed description of the Technology

Description:

Eco fogón mejorado modelo justa, se utiliza en los hogares de las familias que habitan en la cuenca del río Dipilto. Esta construido de ladillo cuarterón, con dos planchas metálicas movibles que forman las hornillas una Chimenea metálica cubierta con malla , en la parte interna lleva una cámara de combustión de ladrillo a una fundición de 1000 °C, también tiene otro compartimento pequeño,para la extracción de residuos producto de la salida de humo. El propósito de esta tecnología es reducir el consumo de leña y disminuir la presión sobre el recurso bosque. Las principales actividades de mantenimiento consisten en: limpieza general del eco fogón, introducir pequeños trozos de leña para lograr el funcionamiento adecuado, en caso de las planchas se limpian cada vez que se finaliza de cocinar, una vez que el nivel de ceniza haya bajado se vuelve a rellenar para mantener el calor. Entre los beneficios e impacto adquiridos por la tecnología se determinan el ahorro del consumo de leña hasta en un 75%, Mayor higiene en la cocina, no hay inhalación de humo por las personas que hacen uso de el, menor cantidad de corte de arboles para ser utilizados de leña. Lo mejor de la tecnología que los usuarios expresan satisfacción por la complementación de la tecnología y no se exponen a enfermedades respiratoria, es fácil de mantenerlo.
