Abstract
A method and an apparatus for continuous real time heating value/coal flow balancing of coal from a coal feeder to a burner. The apparatus includes a Dual-energy Gamma Attenuation (DGA)/Multi-energy Gamma Attenuation (MGA) device for measuring coal quality at a specific location between the coal silo/bunker and the coal feeder in a coal fired plant in order to control the individual burner stoichiometries according to the measured coal quality. By strategically placing the DGA/MGA device, continuous accurate real-time coal quality information is accomplished for making individual adjustments in order to improve stoichiometry to optimize performance of the system.
