<p><P>PROBLEM TO BE SOLVED: To provide an extraction method and a device for cement kiln discharge gas, in which the generation of coating in an extraction processing device for cement kiln discharge gas is stably suppressed with a simple treatment device in an extraction facility for the kiln discharge gas, which excludes compounds with low melting points after condensation by extracting and cooling a part of the discharge gas of an apparatus for manufacturing cement clinker. <P>SOLUTION: The kiln discharge gas facility is provided with: an extraction probe for extracting kiln discharge gas; a cooling room equipped with a blowing section which is connected to the extraction probe and for blowing air for cooling; and a connection tube for passing the discharged gas and air for cooling from the cooling room; wherein the extraction tube is a single tube and inner diameters of the cooling room and the connection tube are substantially equal. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
