No.1-25 Quality evaluation and investigation of co-combustion behavior of torrefied pellet

Abstract

Co-combustion of coal and woody biomass is caught on coal fired power generation in order to reduce CO₂ emission. Measures to increase the co-combustion rate of woody biomass are being studied for the purpose of achieving a larger CO₂ reduction. So, torrefied pellet have attracted attention in order to increase energetic density and to improve grindability.

Physical properties (water absorbability, brittleness), low-NOx combustibility and electrostatic precipitator property were investigated as practical characteristics evaluation when torrefied pellet were used in coal boilers.
