Gas flow in induration furnaces is a critical parameter for iron ore pellet productivity and quality. A triboelectric flowmeter, which measures the gas flow based on the speed of fine particles present in the gas, has been installed in the ducts of a travelling grate at ArcelorMittal Mining Canada (AMEM) in Port-Cartier since June 2011. When combined with the standard instrumentation found in furnaces (temperature, pressure, etc.), it enables a better understanding of the conditions prevailing in the furnace and a better control and thus a more cost effective process. In this paper, the triboelectric flowmeter technology and its implementation and performance at AMEM pellet plant will be described.
