Abstract
Official abstract text for this publication.
The present invention relates to a biomass solid fuel obtained by steam exploding and then molding biomass into biomass blocks and then heating the biomass blocks, wherein the biomass solid fuel has a fuel ratio of 0.2 to 2.5, a dry-based higher heating value of 5,000 to 7,500 (kcal/kg), a molar ratio of oxygen O to carbon C (O/C) of 0.1 to 0.6, and a molar ratio of hydrogen H to carbon C (H/C) of 0.5 to 1.35.
First claim
Opening claim text (preview).
The invention claimed is: 1. A biomass solid fuel obtained by steam exploding and then molding biomass into biomass blocks and then heating the biomass blocks at 150 to 400° C., wherein the biomass solid fuel has a fuel ratio of 0.2 to 2.5, computed by dividing the weight percent of fixed carbon by the weight percent of volatile matter, a dry-based higher heating value of 5,000 to 7,500 (kcal/kg), a molar ratio of oxygen O to carbon C (O/C) of 0.1 to 0.6, and a molar ratio of hydrogen H to carbon C (H/C) of 0.5 to 1.35, wherein the biomass solid fuel is wood-based and/or herbaceous, wherein the COD of an immersion water used for water immersion of the biomass solid fuel is 3,000 ppm or less, and, wherein the biomass solid fuel has a grindability index (HGI) of 20 or more and 60 or less. 2. The biomass solid fuel according to claim 1 , wherein the biomass blocks are pellets or briquettes. 3. The biomass solid fuel according to claim 1 , wherein the COD of an immersion water used for water immersion of the biomass solid fuel is 300 ppm or less.
