Gasification of RDF (refuse-derived fuel) in a pressurized fluidized bed

; ; ;
The pressurized thermal gasification of refuse-derived fuel (RDF), provides an alternative option to the current available municipal solid waste (MSW) disposal methods. A pressurized fuel gas from RDF offers a flexible product in terms of distribution, use, and environmental control benefits and eventually, a combined-cycle power generation. RDF gasification process research began at IGT in a process development unit (PDU) with an exploratory test of pressurized, fluidized-bed gasification conducted at 300 psig and 1450/degree/F at a feed rate of about 800 lb/h. These test results under air-blown conditions are presented in detail: the gas yield composition and the condensible liquid yield and composition. Analysis of the initial pressurized gasification test and a thermobalance decomposition test of the RDF feedstock indicated that the RDF char carbon was not completely converted under the test conditions. Changes in the process operating conditions are suggested to achieve complete carbon conversion in the single-stage, fluidized-bed gasifier. In developing a broad and sound technology base on pressurized RDF gasification, a variety of RDF feedstocks need to be tested with process information gathered for gas cleanup, ash disposal, and process control in response to short-term feed variation. 3 refs., 5 figs., 3 tabs.
