Fire Risk Assessment of Spruce Pellets

Abstract: In the presented paper is assessed fire risk of pellets made from spruce wood (Picea abiesL.) without bark, processed by hot pressing without the use of additional chemicals. Fire risk was assessed on the basis of heat release rate (HRR), the specific carbon monoxide production rate (SCPR) and the time dependence of the induction period of spontaneous ignition on temperature. HRR and SPCR were determined on the cone calorimeter test performed according to ISO 5660-1:2002 standard. Samples were loaded by 20 kW/… Show more

“…The highest mass loss rate of the U-LD samples (up to a time of 300 s) was 0.130%•s −1 , reached in 60 s. The U-HD samples had the highest mass loss rate (up to a time of 300 s) of 0.100%•s −1 , reached in 70 s. The highest mass loss rate of the U-LD samples during the whole testing period was 0.22%•s −1 at a testing time of 450 s due to spontaneous sample combustion. The sudden increase in the mass loss rate of untreated samples occurs at a testing time of about 300 s. In this case, it was the second peak of the maximum mass loss rate, which, according to several authors [62][63][64], occurred in untreated wood. It caused spontaneous combustion or ignition of the samples.…”

“…The analysis was always performed between two sample groups with the same retardant treatment but different densities. The The sudden increase in the mass loss rate of untreated samples occurs at a testing time of about 300 s. In this case, it was the second peak of the maximum mass loss rate, which, according to several authors [62][63][64], occurred in untreated wood.

“…Similar flash point temperatures (of approximately 487.9 °C) of spruce wood were also reached in the work by Hagen et al [ 41 ]. The inductive period, an interval of 460–560 °C, of spruce pellets was described by Martinka et al [ 42 ]. The flammability point temperature (478 °C) of pine wood was investigated by Delichatsios et al [ 43 ].…”

“…Martinka et al [5] assessed the fire risk of thermally unmodified and thermally modified spruce wood according to ThermoWood -Thermo-S and Thermo-D programme by means of cone calorimeter. Thermally modified spruce wood showed lower average and maximum heat release rate and higher total carbon monoxide yield (in full time period of test from 0 to 1800 s).…”
