Abstract

Molding-biomass has been utilized in a 300 MW pulverized coal furnace, and biomass was ground using the existing mill system, without any apparatus addition. The possibility of biomass grinding and the security of mill operating was analyzed, and the effects of biomass-cofiring on combustion flame, furnace temperature profile, furnace efficiency and pollution emission were also investigated. Results show that, roller mills and direct blowing puverizing system can be used to grind molding-biomass and to transport biomass particles. During the processes of biomass co-firing, the flame of biomass injector is stable. Both outlet temperaure of furnace and air preheater decreases after the biomass injection. When the pulverized coal furnace is operated under the biomass co-firing condition, the furnace efficiency is lowered. NO_x and SO₂ emission also decreases with the biomass quantity increasing. The results would provide a guidance for biomass co-firing on the exsiting pulverized coal furnace in China.
