Tóm tắt

 The main purpose of this project is to look at technologies and philosophies that would help reduce the costs of an Integrated Gasification Combined Cycle (IGCC) plant, increase its availability or do both. GE?s approach to this problem is to consider options in three different areas: 1) technology evaluations and development
  2) constructability approaches
  and 3) design and operation methodologies. Five separate tasks were identified that fall under the three areas: Task 2 ? Integrated Operations Philosophy
  Task 3 ? Slip Forming of IGCC Components
  Task 4 ? Modularization of IGCC Components
  Task 5 ? Fouling Removal
  and Task 6 ? Improved Slag Handling. Overall, this project produced results on many fronts. Some of the ideas could be utilized immediately by those seeking to build an IGCC plant in the near future. These include the considerations from the Integrated Operations Philosophy task and the different construction techniques of Slip Forming and Modularization (especially if the proposed site is in a remote location or has a lack of a skilled workforce). Other results include ideas for promising technologies that require further development and testing to realize their full potential and be available for commercial operation. In both areas GE considers this project to be a success in identifying areas outside the core IGCC plant systems that are ripe for cost reduction and ity improvement opportunities.
