Continuous real time heating value (BTU)/Coal flow balancing meter

摘要

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 and the mill 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.
