Abstract

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.

Claims

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, 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.

2. The biomass solid fuel according to claim 1, wherein the biomass blocks are pellets or briquettes.
