Abstract: A duct intersection comprising a first duct portion and a second duct portion extending laterally from a side of the first duct portion. At least one flow modifier is mounted inside one of the first and second duct portions. The flow modifier is a contoured duct liner and/or the flow modifier includes at least one turning vane. The duct intersection may also include a transition portion extending between the first and second duct portions, wherein the transition portion has a length extending along a side of the first duct portion and a depth extending away from the side of the first duct portion, wherein the length is greater than a diameter of the second duct portion.

Abstract: Systems and methods for particle leak detection generally include a separation or collection device configured to filter particulate from a stream and a detection device downstream of the separation or collection device. The detection device can be positioned to detect particulate that passes the separation or collection device and can include a probe configured to detect the solid particles. The particle leak detection systems can be configured to be disposed on moveable systems, such as moveable systems in coke oven operations.

Abstract: The present technology, is generally directed to integrated control of coke ovens in a coke plant in order to optimize coking rate, product recovery, byproducts and/or unit lime consumption Optimization objectives are achieved through controlling certain variables (called control variables) by manipulating available handles (called manipulated variables) subject to constraints and system disturbances that affect the controlled variables.

Abstract: The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.

Abstract: The present technology is generally directed to systems and methods for removing mercury from emissions. More specifically, some embodiments are directed to systems and methods for removing mercury from exhaust gas in a flue gas desulfurization system. In one embodiment, a method of removing mercury from exhaust gas in a flue gas desulfurization system includes inletting the gas into a housing and conditioning an additive. In some embodiments, conditioning the additive comprises hydrating powder-activated carbon. The method further includes introducing the conditioned additive into the housing and capturing mercury from the gas.

Abstract: The present technology is generally directed to methods of increasing coke production rates for coke ovens. In some embodiments, a coal charging system includes a false door system with a false door that is vertically oriented to maximize an amount of coal being charged into the oven. A lower extension plate associated with embodiments of the false door is selectively, automatically extended beyond a lower end portion of the false door in order to extend an effective length of the false door. In other embodiments an extension plate may be coupled with an existing false door having an angled front surface to provide the existing false door with a vertically oriented face.
