Feasibility Studies to Improve Plant Availability and Reduce Total Installed Cost in IGCC Plants
Performer: General Electric
Project No: FE0007859
The project team will complete five techno-economic studies focused on various aspects of IGCC plants where it is anticipated that technological improvements will substantially improve cost-effectiveness and availability of the plants. For power plants and their components, availability is the percentage of time a plant or unit is capable of operating. Availability is reduced by planned and unplanned maintenance and forced outages.For each study area or technology concept, the team will identify system and component-level requirements; develop designs and materials as required for technical evaluation of the concept; validate and test components/sub-systems; and develop appropriate operating methodologies, simulations, and control philosophies where applicable. Eastman Chemical Company will be supporting the GE Energy effort for certain technologies by providing consulting for the technical evaluations and technology transfer phases of the project. The five study areas for improvement of the costs and/or availability of IGCC plants are as follows:
Integrated Operations Philosophy. This study will address equipment sparing, isolation of equipment for maintenance, and other means with the goal of reducing the plant’s total installed cost and/or construction schedule resulting in improved operability and accelerated plant maturity.
Slip Form Components. This study will investigate components or structures that can be slip-formed (e.g., flue gas stacks, cooling tower shells, coal silos) with the goal of reducing the plant’s total installed cost and/or schedule. Conventionally, these structures may be long-lead construction items,
Modularization of Plant. This study will identify and evaluate components or systems of a plant that can be modularized and/or pre-commissioned with the goal of reducing the plant’s total installed cost and/or schedule.
Fouling Removal System. In this study the team will develop a system which will remove the fouling deposits on the heat exchanging tubes in the syngas cooler thereby increasing efficiency and lowering the cost of electricity of the plant.
Improved Blow Down System for Slag Handling. This study will focus on an improved system for slag handling that will increase availability and/or decrease the cost of the plant.
