Document Type and Number:
WIPO Patent Application WO/2018/230715
Kind Code:
A1
Abstract:
Provided are: biomass-derived fuel pellets which have a high calorific value and rarely deteriorate boilers; a system for utilizing a biomass as a fuel source; and a method for producing biomass-derived fuel pellets. The following steps are included: a crushing step 131 of crushing a raw material 111 composed of palm empty fruit bunches in such a manner that the elution of potassium from the raw material 111 can be promoted, and then mashing the resultant fibers; a washing step 132 of washing a crushed product 112 produced by the crushing in the crushing step 131 with warm water to remove potassium from the crushed product 112; a drying step 134 of reducing the water content in a washed product 113 from which potassium has been removed in the washing step 132 to produce a dried product 114; a carbonization step 136 of removing chlorine from the dried product 114 in which the water content has been reduced in the drying step 134 to further reduce the water content, thereby carbonizing the dried product 114; and a granulation step 138 of granulating a carbonized product 117 that has been treated in the carbonization step 136 in the form of a fuel.
