I'm trying to break a url that is part of the figure's caption. I used \burl but didn't work. What can I do?
This is my main code:
\documentclass[11 pt, letterpaper, oneside, openright]{book}
\listfiles
\usepackage[spanish]{babel} % Manejo de idiomas}
\usepackage[utf8]{inputenc}
\usepackage{csquotes}
\usepackage[pages = some]{background}
\usepackage{tabularx}
\usepackage{epigraph}
\usepackage{kantlipsum}
\usepackage{nomencl}
\usepackage[acronym]{glossaries}
\usepackage{graphicx}
\graphicspath{ {imagenes/} }
\usepackage[style=ieee, backend=biber]{biblatex}
\bibliography{bibliografia}
\usepackage{hyperref}
\PassOptionsToPackage{hyphens}{url}
\usepackage{caption}
\glsenablehyper
\usepackage{tikz}
\usetikzlibrary{mindmap}
\usepackage{geometry}
\geometry{
letterpaper,
left=20mm,
right=20mm,
top=30mm,
bottom=30mm,
}
\begin{document}
\include{Chap2}
\end{document}
This is my Chap2.tex code:
\begin{figure}[t]
\includegraphics[width=\textwidth]{calderacarbon.jpg}
\captionof{figure}{Diagrama de una caldera de carbón pulverizado.}
\captionsetup{font={footnotesize,it}, width=\textwidth}
\caption*{Fuente: Valvexport, Inc. \url{http://www.valvexport.com/soluciones-para-alimentacion-y-combustion-de-carbon-pulverizado.html}}
\label{fig:Calderacarbon}
\end{figure}
And this is my result:

Thanks for your help
EDIT: I also used \usepackage[hyphens]{url} but as I'm using {hyperref} I need to put it in the following way
\usepackage[colorlinks=false]{hyperref}
\PassOptionsToPackage{hyphens}{url}
But this doesn't work either

\usepackage[hyphens]{url}? – Werner Apr 15 '15 at 17:03\PassOptionsToPackage{hyphens}{url}was not executed early enough. – Karalga Apr 16 '15 at 17:31
