| 摘要 |
<p>The invention relates to a biomass transport system (1) chiefly for the feeding of bio fuel to a furnace (8) in a bio fuel firing plant (7), comprising at least one worm (15) with at least one centre shaft (22) and at least one helix plate part (23). The biomass transport system (1) also comprises at least one drive element (9) for the rotation of said worm (15) around its longitudinal axis, and at least one outer pipe (12) which substantially surrounds said least one worm (15) for the whole of the longitudinal transporting length (T) of the worm (15), and where said outer pipe (12) further comprises a feed-in opening (14) and a discharge opening (13). The biomass transport system is characterised in that said least one outer pipe (12) and said least one worm (15) are displaceable in relation to each other in the longitudinal direction. The invention also relates to a bio fuel firing plant (7) and a method for the feeding of bio fuel to the furnace (8) in a bio fuel firing plant (7). Finally, the invention relates to a method of safeguarding against backfire through a biomass transport system (1), and the use of a biomass transport system (1).</p> |
