  • Experience on coal reburn in a utility boiler

    Reburning is an in-furnace combustion modification technology for the reduction of NOx. By staging the introduction of the fuel, an environment is created where NOx generated by the combustion of the main fuel supply is subsequently consumed by the hydrocarbon radicals arising from the reburn fuel under reducing conditions. ENEL has retrofitted unit No. 4 of Vado ...

  • A novel approach for modelling of NOx emission reduction in a tangentially fired coal boiler

    In this research paper, predictive modelling of NOx emission of a 210 MW capacity pulverised coal–fired boiler and combustion parameter optimisation to reduce NOx emission in flue gas is proposed. The effects of oxygen concentration in flue gas, coal properties, coal flow, boiler load, air distribution scheme, flue gas outlet temperature and nozzle tilt were studied. The data collected from ...

  • Relative Accuracy Testing of an X-Ray Fluorescence-Based Mercury Monitor at Coal-Fired Boilers

    ABSTRACT The relative accuracy (RA) of a newly developed mercury continuous emissions monitor, based on X-ray fluorescence, was determined by comparing analysis results at coal-fired plants with two certified reference methods (American Society for Testing and Materials [ASTM] Method D6784-02 and U.S. Environment Protection Agency [EPA] Method 29). During the first determination, the ...

  • Mercury speciation and distribution in a 660-megawatt utility boiler in Taiwan firing bituminous coals

    Mercury speciation and distribution in a 660-MW tangential-fired utility boiler in Taiwan burning Australian and Chinese bituminous coal blends was investigated. Flue gases were simultaneously sampled at the selective catalytic reduction (SCR) inlet, the SCR outlet, the electrostatic precipitator (ESP) outlet, and the stack. Samplings of coal, lime, bottom ash/slag, fly ash, and gypsum slurry ...

  • Flue gas Hg measurements from coal-fired boilers equipped with wet scrubbers

    The U.S. EPA has indicated they are considering additional SO2 and NOx emission reductions, and EPA is under a consent agreement to propose mercury reduction regulations by 2004 for the utility industry. The boiler manufacturers and the utility industry have developed improved combustion modification techniques to reduce NOx emissions. These advanced ...

  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...
