O2/CO2气氛下沙柳燃烧特性及动力学研究
study on combustion characteristics and kinetics analysis of Salix under O2/CO2 atmosphere
摘要
Abstract
In this paper, TG-DTG-DTA was adapted to study the combustion characteristics of Salix with different concentrations of O2/CO2. The methods of Coats-Redfern and Malek have been applied to kinetics study during the two periods of the volatiles combustion and coke combustion. The results show that: with the increase of O2 concentration, the firing temperature of Salix increased, the temperature at the maximum burning rate and at the burning up decreased, the residual residue was reduced. Flammability index, burnout index and comprehensive combustion characteristics index show increasing trends. The mechanism function of the volatiles combustion stage is changed from chemical reaction F3 to nucleation and growth A1. The mechanisms function of the coke combustion change from two-dimensional diffusion into one-dimensional diffusion. Both of the apparent activation energies E and the frequency factor A increase with the increasing of O2 concentration.关键词
