Abstract
Se proporciona un gránulo de combustible basado en biomasa, dicho gránulo de combustible que incluye material polimérico termoplástico y una cantidad substancial de material celulósico, v. gr., material celulósico derivado de fuentes de biomasa. El gránulo de combustible comúnmente incluye alrededor de 5 a 15% en peso del material polimérico termoplástico y cuando menos alrededor de75% en peso de material celulósico. Opcionalmente, el gránulo de combustible puede comprender un aditivo de lignina. En ciertas modalidades, puede ser deseable producir los gránulos de combustible de una mezcla de combustible que está substancialmente libre de material de cera añadido. Muchas modalidades de los gránulos de combustible son apropiados para usarse en un horno encendido por carbón y/o en otras aplicaciones de caldera industrial.
Description
combustible triturados se pueden fraccionar para obtener montones de gránulos con tamaños diferentes, v. gr., para separar una mezcja de gránulos de combustible triturados en dos o más montones basados en características de tamaño.
