喷流-移动床RDF热解燃烧温度和气体分布

TEMPERATURE AND GAS COMPOSITION PROFILES OF RDF PROLYSIS AND COMBUSTION IN SPOUTING-MOVING BED

根据RDF (RefuseDerivedFuel)先部分燃烧部分热解然后再气相燃烧的设想 ,设计了下部为喷流 移动床热解室、上部为气相燃烧室的两段反应器 ,对实验室中制备的RDF在该反应器中进行部分燃烧部分热解然后气相燃烧的性质进行了研究 .RDF颗粒连续加入到热解室中 ,实现了在少量空气作用下部分燃烧并在较低温度下部分热解 ,热解气体与二次空气在上部燃烧室中高温燃烧 .主要考察了喷动气量 。

Based on the concept of RDF(Refused Derived Fuel) pyrolysis by partial combustion and subsequent gas combustion, a reactor with two reaction zone (a spouting-moving bed pyrolyzer and a gas combustor) was developed, which was proposed for thermal disposal of solid wastes especially RDF. The RDF produced in the authors'laboratory was used to evaluate the performance of the reactor. RDF was continuously fed to the spouting-moving bed pyrolyzer in which RDF was partially burned to supply heat for pyrolysis of RDF at a lower temperature, then the pyrolysis product gas was burned with secondary air at a higher temperature in the upper combustor. The flow-rate effects of spouting air, auxiliary air and secondary air on the profiles of temperature and pyrolysis gas composition were measured.
