Abstract: The present disclosure is directed to an additive mixture and method for controlling nitrogen oxide(s) by adding the additive mixture to a feed material prior to combustion.

Abstract: A contaminated gas stream can be passed through an in-line mixing device, positioned in a duct containing the contaminated gas stream, to form a turbulent contaminated gas stream. One or more of the following is true: (a) a width of the in-line mixing device is no more than about 75% of a width of the duct at the position of the in-line mixing device; (b) a height of the in-line mixing device is no more than about 75% of a height of the duct at the position of the in-line mixing device; and (c) a cross-sectional area of the mixing device normal to a direction of gas flow is no more than about 75% of a cross-sectional area of the duct at the position of the in-line mixing device. An additive can be introduced into the contaminated gas stream to cause the removal of the contaminant by a particulate control device.

Abstract: An agglomerate is provided that can include an aluminosilicate (ash) base material and one or more of a binding agent or leach reduction agent. Each of the agglomerate and binding agent can include no more than about 25 wt. % cement.

Abstract: A system, method, and computer readable medium are provided that monitors at least one of an input and output stream for at least one of a presence of a material of interest and a concentration of the material of interest; when the material of interest is present and/or has at least a threshold concentration, directs the at least one of an input and output stream to a waste location or path to discard the material of interest; and when the material of interest is either not present or does not have at least a threshold concentration, directs the at least one of an input and output stream to a byproduct location or path to recover the material of interest.

Abstract: The present invention is directed to additives for coal-fired furnaces, particularly furnaces using a layer of slag to capture coal particles for combustion. The additive(s) include iron, mineralizer(s), handling aid(s), flow aid(s), and/or abrasive material(s). The iron and mineralizers can lower the melting temperature of ash in low-iron, high alkali coals, leading to improved furnace performance.

Abstract: A flue gas additive is provided that includes both a nitrogenous component to reduce gas phase nitrogen oxides and a halogen-containing component to oxidize gas phase elemental mercury.

Abstract: The present disclose is directed to a method for controlling iodine levels in wet scrubbers, and, in particular, recirculating wet scrubbers by removing the iodine from the scrubbing solution, such as by using ion exchange, absorption, adsorption, precipitation, filtration, solvent extraction, ion pair extraction, and an aqueous two-phase extraction.

Abstract: A composition is provided that includes a carbonaceous feed material to be combusted to generate an off-gas and an identifier. The identifier is associated with a predetermined composition, characteristic or property of the feed material or the off-gas.
