Dear Crispin and all, Three years ago, I developed a formula for coal briquettes and pellet that are easy to light and provide good flame instead of radiant heat. Typical flame is pink-transparent, depending on used additive to convert the radiant heat to flame. Latter, I learned that coal pellet is better than coal briquette.
The feedstock is low grade coal, which is abundant in Mongolia. Please check the video in the following link: http://www.youtube.com/watch?v=8YXrPyGz1pU Kind regards M. Nurhuda > Dear Stove Buildings and Testers > > > > Testing has restarted at the SEET lab after a major move to a new location > at the Mining Research Institute north of the city.
