| 中文摘要: |
| 研究了以干木质颗粒作为燃料,以空气—水蒸气作为气化剂的户用高热值燃气生物质气化炉,利用Fluent14.0模拟了水蒸气入口距离气化炉内炉栅位置高度h、空气入口流量V0与水蒸气入口流量Vs这三个参数对CO、H2和CH4的体积浓度和燃气热值影响,并采用实验验证数值模拟的结果.研究的结果表明:若水蒸气入口位置高度h=195 mm,水蒸气入口流量Vs=1.41 m3/h时,空气入口流量V0=0.86 m3/h,生物质燃气燃烧热值最大为Q=9.95 MJ/m3,相比单一空气气化剂作用下提高了98.21%. |

| In this research,with woody particles as fuel and air-steam as gasification agent,the high heating value gas biomass gasifier uses numerical value of software Fluent 14.0 to simulate the impact of the three parameters,the position height ‘h’ from the entrance of steam to the gasifier grate,the air inlet flow V0 and the steam inlet flow Vs,on CO,H2 and CH4 volume concentration and gas calorific value and use experiment to verify the result of numerical simulation.The results of research show that when the position height ‘h’ is 195 mm,the steam inlet flow Vs is 1.41 m3/h and air inlet flow V0 is 0.86 m3/h,the combustion of biomass gas calorific value arrives its top,the value is Q=9.95 MJ/m3,which is 98.21% higher than when single gas agent is used. |
