The Experimental Research Of Biomass Gas In Replacement Combustion Process

In recent years,the emission reduction of greenhouse gas CO₂ became increasingly the focus.In Chemical-looping combustion system,the fuel and air did not contact directly,and the oxygen carrier transferred oxygen between the fuel and air.The separation of CO₂ could be achieved in the reaction process,and it was significant for the emission reduction of CO₂.The pyrolysis and combustion characteristics of five biomass from Tibet were investigated by using TGA,and the dynamics parameters were determined,which would provide basic data for the promotion of replacement combustion in Tibet and the in-depth study of solid biomass fuels.This paper has simulated the thermal balance process of replacement combustion between Fe₂O₃ and gaseous fuel and analyzed the conditions including temperature and pressure.The reaction characteristics between Fe₂O₃ and gaseous fuel in different conditions were researched basing on fluidized bed and GC/MS.The results showed that it was suitable when temperature was 1113.15K;the reactivity of Fe₂O₃ had no obviously change,which showed that the Fe₂O₃ particles had good cycle characteristics.
