Patent ID: 7556674

Claim:
A method of separating particles from a flue gas flow that flows substantially horizontally from a first position to a second position in a horizontally extending flue gas duct having a lower portion comprising the steps of: subjecting the particles to deflection in the first position of the horizontally extending flue gas duct downwards to the lower portion of the horizontally extending flue gas ducts, wherein the particles are deflected downwards at an angle of 40 degrees-70 degrees to the horizontal plane of the horizontally extending flue gas duct; dividing the flue gas flow in the second position of the horizontally extending flue gas duct into both a first partial flow containing the deflected particles that is deflected to the lower portion of the horizontally extending flue gas duct and flows downwardly into a collecting chamber, and a second partial flow; and collecting in the second position of the horizontally extending flue gas duct the particles from the lower portion of the horizontally extending flue gas duct.
