Capacitance Tomography

Accurate measurement of the concentration of pulverized-coal in various pipes as a guidance to proper control plays a key role in assuring safe and economic operation of a pulverized coal-fired boiler during the combustion process. Experimental studies are carried out on the measurement of a lean mass flow in a pneumatic conveying pipeline using electrical capacitance tomography (ECT). A cyclone separator is employed in this system where the sensors are placed in order to compensate the inhomogeneity of the sensor sensitivity. The distribution of void fraction in radial direction, the average void fraction and the wavy characteristics are analyzed. The feasibility and reliability of the method are verified by the experimental results.
