Coal Materials Handling: Coal-Feeder Development, Phase I. Third Quarterly Technical Progress Report, April-June 1981

摘要

The objective of Phase I of the program is to demonstrate extended operating capabilities of the Linear Pocket Feeder (LPF). This has required extensive modifications to both the test facility and the LPF in order to effectively conduct extensive testing with both coarse and pulverized coal (PC) at increased operating pressures. Initial tests with PC conducted in the last quarter were successful in that LPF operation with fine coal sizes was demonstrated. However, these tests also showed that the facility and LPF modifications required to conduct the test program were more extensive than originally planned, and that the direction of effort needed to be modified accordingly. Although it was originally projected that the necessary modifications could be initiated without affecting the performance testing phase of the program, this has not proven to be the case. Procurement delays and additional effort required for equipment development have necessitated a reduction in scope of Phase I testing. We currently project that facility and LPF operation at increased operating pressures for both coarse and fine coal sizes can be demonstrated in this phase of the contract, but extended performance testing will have to be delayed until Phase II. Current status may be summarized as follows. Design work and/or specification of commercial equipment required for LPF and facility modification has been completed.Procurement is substantially complete, except for the coal stripping/gas recirculation system which is not necessary for startup. Installation of components is nearing completion, with system startup anticipated in early August. The flow visualization model has been assembled and is operational. Methods for measuring moisture have been developed. (ERA citation 06:029837)
