COMBUSTION PROPERTIES OF MIXED BLACK LIQUOR SOLIDS FROM LINTER AND REED PULPING

摘要：

　　The physicochemical properties of the black liquor solids from linters pulping and black liquor solids from reed pulping were analyzed.The swelling volume index,calorific value,and pyrolysis characteristics of 5 samples of mixed balck liquor solids were tested.The kinetics of the combustion process of the samples was further studied.The results showed that the calorific value and swelling index of the reed black liquor are higher and its inorganic content is lower..Their combustion may be divided into four stages:(1)drying,(2)devolatilization or pyrolysis,(3)char burning,and(4)smelt coalescence.With the increase of reed pulping black liquor solids in the sample,the activation energy was found to decrease,while the frequency factor increase.As a result,the combustion performance of the mixed solids was significantly improved.
