Table 3 shows the physical parameters of the fuel briquettes. The results indicate
that the calorific value of the briquettes was 24MJ kg1 and could be used as a fuel
for combustion in industrial and other boilers. The waterproof limit of the samples
was 10 minutes, which is not enough for storage under natural conditions. It would
be necessary to store the briquettes under cover or to transport them in closed
containers.
