Abstract

Abstract: In this paper combustion characteristics of tobacco stalk was studied. Simultaneous thermal analysis technology was used to analyze the influence of heating rate and particle diameter. Then combustibility index and kinetic energy were obtained. The effect of combustion characteristic index during pyrolysis or combustion reaction tobacco stem of heating rate on biomass of tobacco stem is S_n(20 K/min)>S_n(15 K/min)>S_n(10 K/min)>S_n(5 K/min).But the effect of with particle diameter 0.425 mm in pyrolysis is S_n(20 K/min)>S_n(15 K/min)>S_n(5 K/min)>S_n(10 K/min) and in combustion reaction is S_n(15 K/min)>S_n(20 K/min)>S_n(10 K/min)>S_n(5 K/min). At the same time, the effect of particle diameter on combustion characteristic index is S_n(0.180 mm)>S_n(0.250 mm)>S_n(0.425 mm).

Key words: Pyrolysis, combustion characteristic index, particle diameter, heating rate
