摘要
在流化床内进行了单颗粒海藻(条浒苔)的燃烧试验,研究了床高、床温和流化风速对条浒苔颗粒燃烧后剩余质量和固定碳残留率的影响,并对各因素的影响程度进行了灰色关联分析.结果表明:床温和流化风速对条浒苔颗粒燃烧后剩余质量和固定碳残留率的影响较大,而床高对其的影响较小;各工况因素影响固定碳燃尽的主次依次为:床温>流化数>床高,在研究工况范围内床温是影响燃烧的最主要因素.
Combustion test of seaweed （Enteromorpha clathrata） particles was conducted in a fluidized bed to study the influence of bed height, bed temperature and fluidized air velocity on the mass of residual seaweed and fixed carbon, while grey correlation analysis performed on the influencing degree of each factor. Results show that bed temperature and fluidized air velocity have great influence on the mass of residual seaweed and fixed carbon, while bed height affects little. The important order of factors influencing the burnout of fixed carbon is in turn as follows： bed temperature 〉 fluidized air velocity 〉 bed height, indicating that bed temperature is the chief factor affecting the combustion of seaweed particles among all the factors studied.
