Abstract |
The report gives results of an assessment of instrumentation for the measurement of coal flowrate (either as a dry solid or in a coal/water slurry) and composition. Also investigated was the appropriateness of EPA/IERL-RTP involvement in the development or evaluation of such devices. Findings for flow measurement hardware were that dry coal flow can be easily and accurately measured using weigh belt devices, and that the mass flow of coal in a coal/water slurry stream can be measured using a flowmeter (electromagnetic flowmeters are preferred) and a nuclear density gage. The most promising analysis concept under development is fast neutron activation, with delivery of a sulfur and ash meter anticipated by the end of 1979. Other techniques, such as X-ray fluorescence, work on only a very small coal sample. It is recommended that further EPA investigation deal with system, rather than component, evaluations. |
