Sorry my bad english, I'm brazilian..
Cool, But it only rendered the PARTACLES, no explosion... It probably is a setting i have or something the rig looks fine in the videos and images you have.
You may be using gpu. if so you will see no smoke. Also make sure you are in the proper cycles or blender reder.
Sadly renders nothing???
Possibly a setting issue.
Bake first, then render
