  • 1.2 Anthracite Coal Combustion

    The most widely used wet scrubbers for anthracite coal-fired boilers are venturi scrubbers. In a typical venturi scrubber, the particle-laden gas first contacts the liquor stream in the core and throat of the venturi section. The gas and liquid streams then pass through the annular orifice formed by theLearn More

  • Capital and Operating Costs of Wet Scrubbers

    For the capital cost of the scrubber, the size factor in the above equation was the MW rating of the boiler. A scrubber is designed for a certain gas velocity and this, is closely relat-ed to the capacity. A separate scrubber was scheduled for each boiler. It is very likely that one scrubber could serve more than one small boiler.Learn More

  • October 25, 2000 MEMORANDUM

    FGD scrubbers are the most commonly used scrubbers on coal-fired utility boilers. These FGD units generally capture more than 90% of the Hg(II) in the flue gas entering the scrubber. Consequently, existing wet FGD scrubbers may lower mercury emissions by about 20% to more than 80%, depending on the speciation of mercury in the inlet flue gas.Learn More
