The first Annual Technical Progress Report for the period ending December 31, 1993, summarizes the work done to date by Tampella Power Corporation and Enviropower Inc. Enviropower Inc.s efforts were concentrated on the Toms Creek PDS (Preliminary Design and Studies). The PDS was based on a Gasification Island size providing coal gas to General Electrics frame 6(B) gas turbine. During the course of the project, the scope of the PDS was expanded to include heat and material balances and selected equipment sizing for an IGCC plant size incorporating General Electrics newly introduced 6(FA) gas turbine. The reasons for this revision were improved plant economics and performance. Tampella Power Corporations efforts were also concentrated on Toms Creek design. Information provided by Enviropower Inc. was used to generate more detailed heat and material balances; P&IDs; equipment and system design; and economic evaluation data. Tampella Power Corporation also performed several site specific heat and material balance calculations and economic analyses to provide the basis for evaluating alternate locations for the Project.
