Simulation of municipal solid waste gasification in two different types of fixed bed reactors

摘要: Abstract Simulation of municipal solid waste (MSW) gasification with air in two different types fixed bed reactors has been carried out by using Aspen plus. One type the is an updraft reactor which can be divided into four sections (drying, pyrolysis, gasification, and combustion), other last that flue gas from combustion section not introduced section. The effect on composition lower heating value (LHV) syngas, heat conversion efficiency, carbon at temperatures equivalence ratios are investigated. results indicate introduction improves efficiency LHV syngas. Carbon increases increase temperature ratio both reactors. concentration each component syngas ratio, but no difference found higher ratio.
