摘要: 利用热分析法(TG-DTG)对麦秆和麦秆成型块分别在10、20和30 ℃/min的升温速率条件下的燃烧特性进行了研究,考察了其燃烧过程、着火温度、燃尽温度,计算了综合燃烧特性指数,并进行了燃烧动力学分析。结果表明:麦秆和麦秆成型块的着火温度在250~260 ℃左右,随着升温速率的增加而增加;综合燃烧特性指数明显高于煤。麦秆和麦秆成型块的燃烧反应遵循燃烧动力学的基本方程,属于一级反应。

Abstract: TG-DTG thermal analysis technology was applied to study the combustion characteristic of wheat straw and wheat straw briquette at different heating rate (10, 20 and 30 ℃/min). Their Combustion characteristics were investigated, such as ignition temperature, burnout temperature, combustion parameters and combustion kinetics. The results showed that ignition temperature of wheat straw and wheat straw briquette were 250-260 ℃ and increased with the increase of heating rate. Combustion parameters of biomass are higher than coal. It indicated that the combustion performance of biomass was better than coal. From the kinetic analysis, combustion reaction of wheat straw and wheat straw briquette follows the basic equation of combustion kinetics and belong to first order reaction.

Key words: biomass, wheat straw, TG-DTG, combustion characteristic, combustion kinetics
