<p>PCT No. PCT/DK87/00067 Sec. 371 Date Feb. 2, 1988 Sec. 102(e) Date Feb. 2, 1988 PCT Filed Jun. 3, 1987 PCT Pub. No. WO87/07701 PCT Pub. Date Dec. 17, 1987.A the method and apparatus for cleaning of flue gas from a boiler, and the recovery of heat from gas, the flue with the flue gas being led from the boiler through a heat exchanger in such a manner that it still has a temperature above the acid dew point. The flue gas is then led to a scrubber tower and is washed with a scrubber fluid from a sedimentation tank. The pH value of the scrubber fluid is measured with a measuring element and a liquid additive base is introduced from a tank. The sediment in the sedimentation tank is fed into a high-speed reactor, from which a basic fluid is led to one or more collection vessels supplied with clean gas from a chimney via a blower resulting in the formation of CaCO3 which, not being easily dissolved, is precipitated. The cleaned base is fed to the tank. The high-speed reactor is supplied with lime water through a ring main and a dosing pump from a lime water plant.</p> |
