Evaluation of a Coriolis Mass Flow Meter for Pulverized Coal Flows

摘要

An investigation of a new Coriolis mass flow meter was carried out to determine the feasibility of using it to meter the multi-phase flow of pulverized coal-transport gas mixtures. The Coriolis meter accurately measured dense phase coal flows on a continuous basis, producing an output which was a linear function of the coal flow. In less dense flows the meter monitored flow fluctuations and slugging, but when slugging became substantial the meter behaved erratically. Because the meter indicates flow fluctuation and slugging, it promises to be a valuable instrument for evaluating new coal delivery systems as well as for monitoring and adjusting flow in established systems.
