The purpose of this study is to develop "Semi-Carbonized Wood-Briquette Fuels (SCWB)" used in the Pulverized coal fired power plant. This study was conducted to clarify reduction effect in GHG for co-combustion in the coal fired power plants and optimum molding conditions of Biomass solid fuels. The experimental results obtained are as follows. (1) Optimum molding temperature of SCWB: Density of SCWB has the highest value when consolidated at thermo-fluid occurrence temperature of material. (2) Reduction effect in GHG: SCWB has the highest reduction of GHG owing to its higher bulk density and better grindability than other fuels. It is found that SCWB are appropriate for co-combustion in the Pulverized coal fired power plant.
