Device for determining coal mass flow through pulverized fuel duct in combustion chamber of pulverized coal burner, has associated optical transmission measuring unit and reflection measuring device

摘要

The device has an associated optical transmission measuring unit (5) and a reflection measuring device (7), by which a determination of respective transmission- or reflection coefficients of a particle flow (9) with a particle size distribution is carried out in a pulverized fuel duct (3) in a respective measuring volume (4). A calculating unit is provided for the calculation of mean free length of the path and effective cross section of a particle density distribution. An independent claim is included for a method for determining a coal mass flow through pulverized fuel duct in a combustion chamber of a pulverized coal burner.
