PFB Coal Fired Combined Cycle Development Report. Design Evaluation Report

摘要

The design review team addressed four major questions: the logic and structure of the design approach; the adequacy and completeness of the preliminary design as the basis for the next step definitive design of a pilot plant; the soundness of the performance projections; and the appropriateness of the risk assessment. The reviewers concluded that the approach is sound and the logic and structure reflect appropriate design disciplines for this stage of the project, the disciplines reflect General Electric practice for complex development projects, and comments by external reviewers suggest these disciplines are not standard in other companies; the preliminary design is a sound basis for the next step provided that the required technology tests confirm the design assumptions. (Most of the required tests are planned, but some areas require additional confirmation); and performance projections at steady-state full load are basically sound and require only minor refinements. Performance projections at part load and under transient conditions require additional effort to provide adequate definition, and no barrier problems are anticipated, but minor design changes could enhance plant load response characteristics. The review team basically agreed with the risk assessment of the design team on the reference plant approach, although this represents a consensus of a broad spectrum of individual opinions on many questions. The review team did point out several areas where additional parallel efforts might improve the design or lessen the risk involved in the reference approach.They specifically expressed concern that some promising technology developments were being discarded prematurely.
