Optimization of Venturi tube design for pipeline pulverized coal flow measurements

WU Zhansong, XIE Fei

Frontiers in Energy 2008, Volume 2, Issue 4,   Pages 369-373 doi: 10.1007/s11708-008-0072-8

Abstract: A Venturi flow meter was designed to accurately measure the mass flow rate of pulverized coal in power plant pipelines. Numerical simulations of the dilute turbulent gas-solid two-phase flow in a horizontal Venturi tube were used to study the effects of Venturi tube geometry on the pressure distribution in the mixture. The results show that Venturi tube geometry strongly influences the metering of the dilute gas-particle two-phase flow. The geometry can be optimized to improve the precision of the measurement and ensure stable measurements. Furthermore, the geometries of three types of Venturi tubes were optimized for an experimental study of pulverized coal mass flow rate measurements.
