Turbine blade test cascade modifications and operations, August 1982-April 1983
Technical Report
·
OSTI ID:6593310
A turbine blade test cascade is installed at the Grimethorpe Experimental PFBC Facility to enable research into erosion and corrosion of turbine blade materials caused by the constituents of the exhaust gas. This report covers commissioning of the cascade loop, from August 1982 to April 1983 and the installation of the blades. During this period, the Facility was operated for 985 coal burning hours, the cascade loop was on line for 553 hours and the test blades exposed for 33.5 hours. The installation of the blades was delayed due to equipment problems. The major problems were: seizure of valves used to discharge hot dust from the exhaust gas clean-up system; and poor performance of a gas path heat exchanger due to dust built-up on heat transfer surfaces. Modifications have been made to improve the reliability and performance of the cascade loop.
