Abstract: An injection device for humidifying a reactor space and injecting and dispersing reagents into the humidified reactor space, including an exterior injection duct for high-velocity gas injection and at least one interior injector for reagent and humidifying agent injection as droplets with a droplet environment. The high-velocity gas ensuring the humidification of the liquid droplet environment and mixing and dispersion of the liquid reagent droplets into the reactor. A multiple injection device system and a method for operating the system are also described.

Abstract: A method of controlling SO3 flue gas concentration in a combustion process utilizing a SCR using a sulfurous fuel, the method steps including: providing a combustion system with low NOx burners and SCR; partially combusting the fuel in a first stage to create a reducing environment; maintaining the reducing environment for a sufficient time period such that SO3 is reduced to SO2 to achieve a desirable level of SO3; combusting the remainder of the fuel and combustion intermediates in a second stage with oxidizing environment; reducing the remaining NOx with the SCR; thereby reducing emissions NOx.

Abstract: A combustion system having improved mercury collection. The system includes a combustion chamber for burning a fuel containing mercury, whereby burning produces a flue gas stream containing mercury and a device for removing mercury from the flue gas stream. The device includes a thermopolymer substrate; and a mercury-receptor attached to the substrate. In one embodiment, the system may further include a collector downstream of the device for collecting the mercury attached to the thermopolymer. The inventions further include alternative methods of mercury removal and preparation of the polymer substrate.

Abstract: A circulating fluidized bed boiler having improved reactant utilization. The circulating fluidized bed boiler includes a circulating fluidized bed having a dense bed portion; a lower furnace portion adjacent to the dense bed portion; and an upper furnace portion, wherein the dense bed portion of the circulating fluidized bed boiler is maintained below the stoichiometric ratio (fuel rich stage) and the lower furnace portion is maintained above the stoichiometric ratio (fuel lean stage), thereby reducing the formation of NOx.; a reactant to reduce the emission of at least one combustion product in the flue gas; and a plurality of secondary air injection ports downstream of the circulating fluidized bed for providing mixing of the reactant and the flue gas in the furnace above the dense bed, wherein the amount of reactant required for the reduction of the emission of the combustion product is reduced.

Abstract: Systems and methods for reduction of pollutants in combustion processes using combined rotating opposed fired air (ROFA) and fuel injection sorbents (FSI) for increased chemical reactivity.

Abstract: A method of extending the droplet half-life of water droplets in a combustion furnace by increasing the relative humidity in the droplets' environment; thereby reducing the evaporation rate of the water from the droplet and increasing the half-life of the droplets in the droplets' environment.
