The test report prepared by NRDC for the PFB heat exchanger tested at the NRDC Leatherhead Facility was received by Curtiss-Wright and results are reported herein. Metallurgical evaluation of the heat exchanger has been completed. The tube materials specimens inserted in one of the Dorr-Oliver client FB reactors accumulated an additional 2600 hours of operating time before being removed. Total time was 4300 hours which exceeded the original goal. The SGT/PFB Technology Rig shakedown testing continued. A revised heat exchanger tube restraint was tested with satisfactory structural results. Coal dolomite and ash system shakedown testing during rig operation has resulted in numerous revisions to system details and operating procedures to alleviate interruptions in feeding and discharging of materials. Design and fabrication were initiated for modifications being incorporated into the SGT rig to test a broad range of candidate PFB tube materials, turbine materials, coatings for the foregoing candidates and several on-line particulate monitoring instruments. Final pilot plant design proceeded from the preliminary design completed last quarter. The specification for the secondary hot gas clean-up system was completed and work is nearly complete on the coal preparation and injection equipment and the dolomite injection equipment specifications. Control system definition and specification of control equipment, valves and instrumentation is continuing.
