Work has been performed in several areas of coal conversion: updating the study of the state-of-the-art of instrumentation, development of mass-flow and other on-line instruments, process control analysis, and organization of a symposium on instrumentation and control for coal conversion. An intermediate Solids/Gas Flow Test Facility (S/GFTF-I) under construction for instrument development, testing, evaluation, and calibration is described. The development work for several mass-flow and other on-line instruments is described: acoustic flowmeter, capacitive density flowmeter, neutron activation flowmeter and composition analysis system, gamma ray correlation flowmeter, optical flowmeter, and capacitive liquid interface level meter. These flowmeters are being developed for two-phase prcess flow lines of coal conversion plants. |
