Outline of Final Research Achievements

A possibility of the new combustion method in which combustion region is formed at one end of a columnar briquette and propagates one dimensionally was investigated. As a result of the combustion experiments in the case with cylindrical briquette, it was confirmed that there is a condition in which the mass loss rate is almost constant. In the condition, it was observed that the flames are formed around the outer periphery at the lower part of the briquette and above the top end, and the long char combustion region was formed above the flame formed around the briquette. In the case of 1100 and 1300 kg/m3 briquette density, both the mass loss rate and the combustion efficiency decreased with high and low air flow rate and, therefore, they have a peak at moderate air flow rate.
