PROOF OF PRINCIPAL TEST TO FEED AND METER GRANULAR COAL INTO 450 psig GAS PRESSURE

PDF Version Also Available for Download.

Description

The objective of this project is to demonstrate proof of principal to feed and meter granular coal into 450 psig gas pressure for use with pressurized fluidized bed combustors. This report summarizes work undertaken in the first quarter of 2000 in support of that objective. At the end of the last quarter the pump had been re-designed to incorporate a larger torque hub and provide a substantial increase in drive train strength to prevent recurrence of failures experienced during earlier testing. Additional modifications were incorporated to improve the performance of the disk seals by improved location and adjustability, and the ... continued below

Description

The objective of this project is to demonstrate proof of principal to feed and meter granular coal into 450 psig gas pressure for use with pressurized fluidized bed combustors. This report summarizes work undertaken in the first quarter of 2000 in support of that objective. At the end of the last quarter the pump had been re-designed to incorporate a larger torque hub and provide a substantial increase in drive train strength to prevent recurrence of failures experienced during earlier testing. Additional modifications were incorporated to improve the performance of the disk seals by improved location and adjustability, and the outlet was modified to incorporate a method to allow rapid adjustment of the outlet sealing column length without pump disassembly and rework being required. This quarter has been largely spent in manufacture of the new parts required, and in initial assembly, alignment and pinning of the revised configuration. The assembly is now complete and the pump is ready for installation into the test rig for the final series of tests.
