Numerical Simulation and Experimental Research on Higher Heating Value Biomass Gas Gasifier

Abstract:

With dry woody particles as fuel and air-steam as gasification agent, the higher heating value biomass gas gasifier used software to simulate the height position h of the steam from the entrance in the gasifier, the steam inlet flow rate V_s and the air inlet flow rate V₀. These three parameters impact on the volume concentration of CO, H₂ and CH₄ and its gas calorific value were analyzed. The orthogonal test were used for design parameters h, V_s and V₀, the optimization values of these three parameters were carried out, and test its volume concentration and gas calorific values. Numerical simulation and experimental results showed that when the height position h=180mm, air inlet flow rate V₀=0.94m³/h, and steam inlet flow rate V_s=1.30m³/h, the combustion of biomass gas calorific value arrives its top, the value is Q=10.98MJ/m³, which is 114.87% higher than when single gas agent is used.
