    摘要： A method to reduce mercury in gas emissions from the combustion of low rank coal in a combustion system, said method including: combusting coal having a low chlorine content in the combustion system, wherein elemental mercury (Hg0) is released in the flue gas produced by the combustion of the low rank coal; releasing chlorine into the flue gas by combusting a coal having a high chlorine in the combustion system; reacting the elemental mercury and released chlorine in the flue gas to oxidize the mercury; adsorbing at least a portion of the oxidized mercury generated by the combustion of the coal with an adsorbent in the flue gas, and collecting the adsorbent with the oxidized mercury in a combustion waste treatment system.

    摘要： In a method to decrease emission of mercury, a factor is selected to control a combustion process to generate a flue gas comprising fly ash with enhanced unburned carbon; the combustion process is controlled according to a factor selected from reburning fuel, flue gas temperature, OFA injection, coal particle size, LNB flow, LNB design, combustion zone air, stoichiometric ratio of fuel, fuel/air mixing in a primary combustion zone and fuel/air mixing in a secondary combustion zone to produce the flue gas comprising fly ash with enhanced unburned carbon and to vaporize mercury; and the flue gas is allowed to cool to collect fly ash with enhanced unburned carbon with absorbed mercury. A system to decrease emission of mercury; comprises a combustion zone that is controlled to generate a flue gas comprising fly ash with enhanced unburned carbon and that produces vaporized mercury; and a post combustion zone to cool the flue gas to collect fly ash with enhanced unburned carbon with absorbed mercury.

    摘要： A method for continuously removing mercury from a supply of combustion gas is provided. The method includes adjusting a power input to an electrostatic precipitator to control a quantity of fly ash emitted from the electrostatic precipitator. A turbulent flow of combustion gas is produced to suspend particulate matter including the quantity of fly ash contained in the supply of combustion gas. A substantial portion of the mercury is absorbed within the particulate matter including the quantity of fly ash. The supply of combustion gas is filtered to remove the particulate matter from the mercury. A quantity of absorption sites available for absorbing mercury is controlled by monitoring an emission of fly ash from the electrostatic precipitator.

    摘要： A method for reducing ammonia emissions in combustion exhaust gases and other waste streams using an oxidation catalyst, whereby unreacted ammonia (ammonia “slip”) is reduced downstream of a Selective Catalytic Reduction (“SCR”) system simultaneously with the reduction of other gaseous pollutants. The invention utilizes a noble metal-based catalyst, such as Pt, Pd or Ru, such that the ammonia is oxidized in the presence of oxygen to a species having a higher oxidation state of nitrogen, preferably elemental nitrogen N2. The efficiency of the process can be increased by optimizing the catalyst operating conditions and adjusting the temperature and space velocity, or the position of the metal-based catalyst relative to the SCR system.
