鼓泡流化床稻草与污泥共气化试验
Experiment of co-gasification of rice straw and sludge in bubbling fluidized-bed
摘要
Abstract
The recycle of industrial and agricultural wastes is important for protecting the environment and conserving resources. The experiment of co-gasification of rice straw and sludge was performed in a bubbling fluidized-bed. The effects of gasification equivalence ratio(ER),material moisture content and sludge mixing ratio on gasification characteristics and tar yield were analyzed,respectively. The results showed that of the ER increased from 0.2 to 0.4,the content of combustible gas,the low heating values (LHV)of syngas and gasification efficiency increased slightly at first and then decreased gradually. The gasification efficiency reached the maximum of 53.8% when the ER was 0.25;Tar yield decreased as the ER increased. When the material moisture increased from 5% to 20%,all the combustible gas content dropped,so did the LHV of syngas,gas yield and gasification efficiency;Tar yield increased first and then reduced. When the sludge mixing ratio increased from 0 to 30%,the concentration of H2 was essentially unchanged,while the content of CO and CH4 increased at first and then reduced. The LHV, gas yield and gasification efficiency reached the best when the sludge mixing ratio was 20%;Tar yield decreased at first and then increased slightly.关键词
