【Abstract】 With the help of an integrated thermoanalyzer of the type STA 409C the characteristics of combustion were analyzed with respect to a mixed sample consisting of one type of coal and two kinds of biomass as well as a sample of the above items mixed in different proportions. The results of this analysis show that after the adding of biomass in the coal the combustion process can be viewed as distinctly divided into two stages with an ignition being realized ahead of the designated time. Meanwhile, better burn-off characteristics were obtained. As a result of the mixing of biomass and coal there emerged an increase in heat generation rate coupled with an enhanced utilization rate of the biomass. Moreover, through an in-depth analysis of thermogravimetric and differential-scanning calorimetry curves the combustion kinetic parameters of the above-cited samples were investigated.更多还原
