Abstract
With the completion of the individual gasifier test reports, attention has been turned to correlating data from all sixteen gasifier tests to evaluate process performance and define scale-up criteria. Efforts were initiated for a similar study with data from the devolatilizer test series. Discussions with Fluidized Bed Research personnel at Westinghouse R and D and a review of their Laboratory program literature identified specific theoretical and empirical models that can be used as an initial basis for comparison of performance parameters. Work was initiated to prepare a hardware evaluation report that will provide a documented history of PDU hardware performance to date, design changes incorporated during the program, and general data and recommendations related to coal gasification plant design. Work has been carried out in the following areas: support tasks for the current PDU combustor-gasifier test program, support tasks for the devolatizer to prepare for integrated plant operation, coal behavior studies, ash behavior studies and reactor analysis.
