dc.description.abstract | Smoldering fires in stored or transported solid biofuels are very difficult to extinguish.
The current study has explored heat extraction from the combustion zone as a method
for extinguishing such flameless fires. Heat extraction from the sample was made
feasible using water flowing through a metal pipe located inside the sample. The fuel
container was a steel cylinder with insulated side walls, open at the top and heated
from below. Wood pellets (1.25 kg, 1.8 liters) was used as fuel. Results from smallscale
experiments provide proof-of-concept of cooling as a new extinguishing method
for smoldering fires. During self-sustained smoldering with heat production in the range
0-60 W, the heat loss to the cooling unit was in the range 5-20 W. There were only
marginal differences between non-extinguished and extinguished cases. Up-scaling is
discussed, cooling could be feasible for preventing smoldering fires in silos. | nb_NO |
