摘　　要：为了研究海藻类生物质和陆生生物质的混烧特性,分别选择海藻类和陆生生物质中具有代表性的条浒苔和稻壳2种物质进行混合燃烧试验(质量比为1∶1),并采用TG-MS-FTIR联用分析仪研究条浒苔、稻壳及其混合物的燃烧过程,采用质谱仪在线监测了H_2O,NO,CO_2,NO_2,SO_2等气体产物,通过MS-FTIR综合分析了燃烧过程中的气体产物.结果表明:燃烧过程大致可分为3个阶段,即水分析出阶段、挥发分析出燃烧阶段、固定碳燃烧与燃尽阶段;混合燃烧可以较大程度地降低NO,NO_2,SO_2等有害气体的排放量;条浒苔完全燃烧的时间要滞后于稻壳,在稻壳燃烧过程中,加入条浒苔能使其提前着火燃烧.To investigate the co-combustion characteristics of marine algae biomass and terrestrial biomass,the combustion experiment was conducted using the mixture of enteromorpha and rice husk with mass ratio of 1 to 1. The combustion processes of enteromorpha,rice husk and the mixture were analyzed by TG-MS-FTIR. The gas products of H_2O,NO,CO_2,NO_2 and SO_2 were monitored online by mass spectrometer. The MS-FTIR technique was utilized for the synthetic analysis of gas products. The results show that the combustion can be broadly classified into three stages of moisture evaporation,release and combustion of volatile and char combustion. The emissions of noxious gases of NO,NO_2 and SO_2 can be significantly decreased by co-combustion. The MS-FTIR analysis of gas products shows that the complete combustion time of enteromorpha is longer than that of rice husk. The adding enteromorpha can make rice husk ignite and combust in advance.
