  • Publication number: 20180258814
    Abstract: A boiler or other fired vessel includes a housing with a burner at one end, a furnace downstream of the burner, a convection section downstream of the furnace and a flue gas outlet downstream of the convection section. A first means for loading a reducing agent comprising at least two injectors is located downstream of the furnace. A second means for loading a reducing agent is located downstream of the first means for loading a reducing agent. A selective catalytic reduction catalyst is located either downstream of the second means for loading a reducing agent or adjacent the second means for loading a reducing agent such that the catalyst is provided to the boiler or other fired vessel approximately simultaneously with the reducing agent from the second means for loading the reducing agent.

  • Patent number: 9255507
    Abstract: A reagent injection system for a catalytic emissions reduction assembly of a combustion turbine that includes an exhaust duct and at least one injector. The exhaust duct includes a first section including an entrance end and an exit end, wherein the entrance end is configured to be fluidly coupled to the combustion turbine to receive exhaust gases therefrom. The exhaust duct also includes and a second section having an entrance end that is fluidly coupled to the exit end of the first section. The at least one injector is operatively coupled to one of the first and second sections, and each injector is configured to inject a reagent into the exhaust gases flowing through the exhaust duct.

  • Patent number: 7635593
    Abstract: Localized catalyst activity in an SCR unit for controlling emissions from a boiler, power plant, or any facility that generates NOx-containing flue gases is monitored by one or more modules that operate on-line without disrupting the normal operation of the facility. Each module is positioned over a designated lateral area of one of the catalyst beds in the SCR unit, and supplies ammonia, urea, or other suitable reductant to the catalyst in the designated area at a rate that produces an excess of the reductant over NOx on a molar basis through the designated area. Sampling probes upstream and downstream of the designated area draw samples of the gas stream for NOx analysis, and the catalyst activity is determined from the difference in NOx levels between the two probes.

  • Patent number: 4795586
    Abstract: Methods and compositions are provided for simultaneous reduction of NO.sub.x and SO.sub.x in combustion effluents and process gas streams, exmploying a sorbent material of calcium or dolomitic lime hydrated with aqueous carboxamides, optionally with carbinol reductants, in amounts sufficient to reduce the NO.sub.x and SO.sub.x concentrations from the effluents. The sorbent material may be introduced as dry powders or wet hydrates in effluent streams at temperatures ranging from 400.degree. to 2400.degree. F.

  • Patent number: 4208386
    Abstract: Method for reducing NO.sub.x in combustion effluents comprising introducing urea at elevated temperatures in the presence of oxygen, either as a solid or solution in amounts sufficient to reduce the NO.sub.x concentration. Conveniently, the urea may be introduced as a solid powder or as a solution in a hydroxylic solvent, at temperatures in excess of 1300.degree. F. and in the presence of at least 0.1 volume percent oxygen.This invention was made under contract with or supported by the Electric Power Research Institute.
