Abstract

ABSTRACT
Due to the urgent need for electricity sources in Egypt, this investigation is an attempt to prepare a metering tool for measuring the flow rate of the suspended gas-solid mixture flows in coal thermal power stations. One of the simplest methods for accurately measuring the flow rate of pulverized coal in the thermal power stations is the venturi meter. In the present work, different geometrical models have been designed and applied for measuring air-coal mixture flow rate, considering the effect of different operational parameters on the pressure sensitivity, pressure recovery and performance of the venturi models. The measurements showed the effects of these parameters on the pressure drop and the pressure distribution. New charts have been deduced from the experimental data for seven non-standard venturi models that shows different effects of particle size, loading ratio and throat length of venturi. From the experimental results a new correlation for two-phase flow discharge coefficient is deduced in the present study and comparison between the experimental and calculated is done with error percentage from +25% to -20%.
