EFFECTS OF QUICK LIME ON COMBUSTION CHARACTERISTICS OF LIGNITE
摘要
Abstract
The effects of quick lime (CaO) on combustion characteristics of lignite was studied by TGA. The comprehensive combustibility parameter S, the combustibility indexes C and the composite indexes on ignition and burning Rw, which can well indicate the combustion characteristics, were adopted. Then the chemical kinetics parameters, i. e. activation energy E and frequency factor A were calculated in this paper. The result showed that: burning process was clearly divided into two phases after addition of quick lime. With the ratio of quick lime increasing, the pre-combustion intensity was gradually weakened, the post-combustion intensity was gradually increased. The content of quick lime reaches 20%, the activation energy of the samples decreased slightly and the maximum burning rate of lignite and quick lime blending was faster than raw coal. But with the amount of quick lime increasing, burnout performance of sample get worse.关键词
