摘要
Several types of tar-free and tar-emitting biomass fuels were gasified in a 0. 864-m-high by 0. 578-m-inside diameter downdraft gas generator. These fuels included charcoal, wood chips, densified refuse derived fuel (D-RDF), and densified digested sewage sludge (d-DSS). An instrumentation system was developed and used to measure the species gas concentration and the profiles of temperature within the reactor. Due to batch operation, the principal periods corresponding to devolatilization and char gasification were observed. Results indicate that the gas quality during these periods cannot be optimized in a single reactor.
