  • METHOD AND APPARATUS FOR CONTROLLING RELATIVE COAL FLOW IN PIPES FROM A PULVERIZER
    Publication number: 20100218591
    Abstract: Pulverizer coal flow pipes feed a mixture of air and coal to burners in electric utility coal fire facilities. A method and apparatus for sensing relative coal flow in the pipes uses acoustic emission (AE) sensors to detect flow in each pipe. Sensed relative flow in the pipes is used to balance flow in the pipes and to further adjust pipe coal flow. Sensed flow is used with control parameters of a furnace to maximize power plant efficiency and to ensure compliance with emissions requirements.
