    16/02/2020· When the general geometries of the FGD absorber, the flue gas ductwork towards the chimney, and the chimney itself are known, an experienced expert should model the system to predict the behaviour of any liquids contained within the flue gas stream. The modelling must include the construction of a physical scale model. (Figure 1) Based on the observations in the

  • Wet Stacks: Friend or Foe? | Power Engineering

    buoyancy of flue gas exiting from the chimney resulting in dispersion of pollutants over a wider area and consequently reduced ground level concentration of pollutants. However, GGH requires additional space, results in additional pressure drop, leakage issues apart from adding to the cost. Even with GGH, chimney flue(s) may require additional protection by way of lining or resistive

  • Flue-gas desulfurization Wikipedia

    Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration. Before flue gas desulfurization was installed, the emissions from the Four Corners Generating Station in New Mexico contained a significant

  • Velocity of the Flue Gas CR4 Discussion Thread

    25/11/2013· Velocity of gas in a stack(V) = Q/kA where k is the coefficient of velocity(0.3-0.5),Q is the volume of gas to be handled in (cfs), V is the velocity (ft/sec) and A is the the cross sectional area of the chimney or stack (ft*2). If a stack is used (as opposed to a chimney) the velocity will be higher due to the smoother internal surfaces.

  • Flue Gas Desulfurization (Acid Gas Removal) Systems

    Gas velocities may be 1.5 to 10 m/s (5 to 30 ft/sec) in tower scrubbers and more than 30 m/s (100 ft/sec) in the throat of a venturi scrubber. A common range of the gas velocity for FGD absorbers is 2.0 to 3.0 m/s (7 to 10 ft/sec). The lower the velocity is, the less the entrainment, but the more costly the scrubber will be.

  • Chimneys for Operation without Flue Gas Reheating after

    12/09/2016· For plant design, this means that reheating of the flue gases after wet flue gas desulfurization is no longer necessary. The consequence would be chimney operation with water-saturated flue gas having a temperature in the 45° C to 63° C range. The increased formation of condensates which this entails, the increased chemical corrosion, the changed internal atmospheric
