Title: Integrated MHD Bottoming Cycle: First quarterly report, September 11--October 31, 1987

Abstract

The Integrated MHD Bottoming Cycle project progress for September and October relates to Task 1--Modification of the Existing Coal Pulverizer and Dryer System, and Task 2--Design, Fabrication, and Installation of an Automated Spent Seed/Ash Handling System. The project team was assembled and committed to the project. Team members attended a kickoff meeting at the Pittsburgh Energy Technology Center. The design approaches for the pulverizer modifications, the spent seed/ash handling system, and the air heater replacement for the existing vitiation heater were presented. Planning was initiated to distribute the authorized funding among the tasks. Work was started on the Management Plan, including the Work Plan, Milestone Schedule Plan, and Cost. This report covers task description and project status for the first two months of the project.

  • The Integrated MHD Bottoming Cycle project, progress for September and October relates to Task 1--Modification of the Existing Coal Pulverizer and Dryer System, and Task 2--Design, Fabrication, and Installation of an Automated Spent Seed/Ash Handling System. Drafts of the Preliminary Design Review packages for the Modification of the Existing Pulverizer and Dryer System and the Automated Spent Seed/Ash Handling System were submitted to DOE/PETC for review. B and W reviewed the system criteria for drying Montana Rosebud coal to 3% moisture. B and W concluded that the system suggested in the RFP would not achieve the required drying. B andmore » W recommended that a pre-dryer be used in combination with drying in the pulverizer. B and W is proceeding to define the performance requirements and costs of a system using a pre-dryer. This report contains a project and task descriptions.« less

  • Integrated MHD Bottoming Cycle project progress for August 1988 through October 1988 was in obtaining and reviewing vendor quotes for the coal dryer and modifying the system to eliminate the necessity of drying in the pulverizer. Vendor preliminary quotes for coal dryers were received. We received reports of drying tests conducted by the vendors. Test results were reviewed, and a decision to do all the drying in the dryer was reached. A final bid was received from one of the three vendors. We received several bids for the pneumatic conveyor portions of the Automated Ash/Seed Handling system. We received onemore » bid and several no bids on the mechanical (screw) conveyor for the system. We have solicited two additional vendors. We plan to select the vendors for the Automated Ash/Seed Handling system in the next quarter, conduct the Critical Design Review and submit procurement approval packages for the equipment during the next quarter. 3 figs.« less

  • The overall objective of the project is to design and construct prototypical hardware from an integrated MHD topping cycle, and conduct long duration proof-of-concept tests of the integrated system at the US DOE Component Development and Integration Facility in Butte, Montana. The results of the long duration tests will augment the existing engineering design data base on MHD power train reliability, availability, maintainability and performance, and will serve as a basis for scaling up the topping cycle design to the next level of development, an early commercial scale power plant retrofit. Progress is reported on the design, fabrication, and testingmore » of components of the MHD power train. 1 fig.« less

  • The Integrated MHD Bottoming Cycle project progress for May through July relates to Task 1--Modification of the Existing Coal Pulverizer and Dryer System, and Task 2--Design, Fabrication, and Installation of an Automated Spent Seed/Ash Handling System and Task 4--Participation on the MHD Technology Transfer Integration and Review Committee. The Preliminary Design Report for the Automated Spent Seed/Ash Handling System was submitted to DOE/PETC for review. The design combination of rotary seal valves, screw feeders, weigh tanks and pneumatic transport was considered acceptable. Modifications of equipment sizes and locations are required to accommodate additional hoppers to be added to the Superheatermore » Test Module and maintain access to this equipment and existing equipment. B and W located vendors who plan to submit quotations for dehumidification equipment needed to recycle inert gas with 3% oxygen to the pulverizer to complete the drying. 3 figs.« less

  • Combustor spare and contingency hardware was shipped to the CDIF. Manufacture of spare and replacement hardware for the lA4 channel and diffuser continued. Fabrication of a modified/spare channel inlet frame which enables iron oxide injection. The cathode power cabinets and associated control system were successfully tested at Westinghouse and met all design requirements. The cathode system was delivered to the CDIF and installed in the current consolidation building. With the delivery of tills component, all prototypical power train components have been delivered to the CDIF. The hot-fire checkout of the channel subsystem and the design verification test series of themore » integrated power train were completed. A total of 29 tests were performed accumulating 120 thermal and 52 electrical hours. The test series demonstrated the adequacy of the overall cooling of the channel subsystem and provided an initial evaluation of the integrated combustor and channel performance in terms of operating conditions, power output, conductivity, heat loss, slagging behavior, and gas-side wear characteristics. During the test series localized wear in the supersonic nozzle was observed on the right sidewall. Cause of wear is being investigated. At conclusion of DVT test series, the channel was removed for inspection.« less
