Research on Insert Double Venturi Tube Measuring Equipment
Abstract
The essay herein analyses and compares the mainly existing problems for the measurement of the air flow that is of lower velocity and in large diameter duct. Through the wind tunnel test, the research is emphasized on the characteristics and mathematical model of the insert double ventrui tube and describes the structure, composition, erection, specialties and application of such tube and its advantages when applied in the measurement and control of assistant combustion air, cool air and coal air (blast furnace coal air, cokery coal air and converter coal air) of the heating furnaces in metallurgy as well as that of the first and secondary air of the boilers and other kinds of air flow of lower velocity and in large diameter duct in thermal power plant.
