Coal Test Program in a Pressurized, Fluidized-Bed Ash-Agglomerating Process Development Unit. Volume 2. Data Analysis. Final Report November 15, 1984-August 31, 1987

摘要

The objective of the project is to extend the ash-agglomerating fluidized-bed gasification data base of important American coals to pressures of 500 psig. A series of gasification tests in IGT's 8-inch process development unit (PDU) with lignite and subbituminous coal produced steady-state data at 100, 200, and 300 psig. After GRI reviewed an analysis of this data, the PDU system was upgraded to 500 psig operating capability. A matrix of gasification tests were then completed with lignite and subbituminous coal at 200, 300, and 450 psig, and material and energy balances were prepared for various set points. A statistical technique has been applied to reconcile the steady-state data estimating maximum likelihood true measurement values while closing all element and energy balances exactly. Science Ventures, Inc. of California has developed such a data reconciliation computer software package known as BALAID. It takes advantage of all available measurement information, as well as information embodied in the conservation laws and in the estimated quality of the measurements. This program has been applied to the steady-state data resulting in improved balances.
