Abstract :
A technique suitable for measuring density profiles of solids inside an ecologically friendly circulating fluidized bed coal combustor is introduced. Employing a microwave locating reflectometer it is possible to perform measurements in the dense phase of the reactor. Improvement of the spatial resolution by using a pole extraction algorithm is discussed.<>
