Abstract
ABSTRACT
The present paper concerns with studying experimentally the mixture of gas-solid
(air-coal) flows in a Venturi meter in an attempt to prepare a metering tool for
suspended gas-solid mixture flows. The different parameters that affect the gas-solid
mixture flows metering process were determined and analyzed. In order to conduct
the study, an experimental set-up was designed and manufactured in the laboratory
of the thermal power engineering in Menoufia University. Furthermore, seven
nonstandard (long-throated) geometrical Venturi models with different diameters
ratios and throat lengths were selected guided by previous literature and
manufactured to be used in the present experimental work. Additionally, the
experimental study was performed on the selected models to determine the effect of
different Venturi meter geometric models on pressure drop sensitivity, pressure
recovery, and to seek a viable method for determining loading ratio for suspended
gas-solid flows in the Venturi. The results showed that the coal loading ratio affected
greatly and positively both the pressure drop and recovery ratios of air-coal mixture
flows in the Venturi. However, inlet and exit geometries of the Venturi had smaller
effect on the pressure drop and recovery ratios than the coal loading ratio and
particles diameter range. Additionally, decreasing the diameters ratio and increasing
the throat length improved the Venturi pressure drop sensitivity to solids loading.
Finally, the experimental results helped greatly to analyze the different parameters
concerning the air-coal mixture flows in a Venturi meter and provided an insight on
the feasibility of using the Venturi as a metering tool for suspended gas-solid mixture
flows in a future continuation of the present work.
