A biomass solid fuel is provided which, when exposed to rain water, has a reduced COD in discharged water and has low disintegration-property, while suppressing an increase in cost. The present invention relates to a biomass solid fuel obtained by molding pulverized biomass, having a fuel ratio (fixed carbon/volatile matter) of 0.2 to 0.8, dry-basis higher heating value of 4800 to 7000 (kcal/kg), a molar ratio of oxygen O to carbon C (O/C) of 0.1 to 0.7, and a molar ratio of hydrogen H to carbon C (H/C) is 0.8 to 1.3.

Biomass solid fuel

A biomass solid fuel which, when exposed to rain water, has a reduced COD in discharged water and has low disintegration-property, while suppressing an increase in cost. The biomass solid fuel obtained by molding pulverized biomass particles, such that mutual bonding or adhesion between pulverized biomass particles is maintained after immersion in water.

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.
