Title: Evaluation of interior Alaska biomass for compressed residential firelogs: Final report

Technical Report ·
OSTI ID:5767169

Unused tree and moss residue from land clearing operations in Interior Alaska was collected, milled, dried, and densified into fuel logs. Moss and four different tree species were used, resulting in six types of raw materials being sampled. All produced a suitable residential fuel. Logs containing a high proportion of moss were less desirable as a residential fuel because of their high ash content. Heating values of each type of raw material were determined. Practicality of converting the material with high moss content into a densified fuel depends on its long-term storage characteristics. Storage in Fairbanks, Alaska, appears to create a problem because the firelogs tend to break down (decompress) when exposed to the extremes in temperature from winter to summer. Logs showed a tendency to elongate to the point of disintegration. 2 refs., 20 figs., 3 tabs.
