Title:
COMBUSTION GAS BLEEDING PROBE AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2023/171460
Kind Code:
A1
Abstract:
Provided are a combustion gas bleeding probe and a method for operating the same capable of adequately cooling bleed gas even if a bleed rate is enhanced, and capable of enabling operation while maintaining a prescribed chlorine removal efficiency. A probe 2 comprises an inner pipe 21 for bleeding a portion of a combustion gas G1 from a kiln 1, and a plurality of discharge ports 25 each of which is provided penetrating through the inner pipe 21 and each of which discharges cold air C in a direction that is perpendicular to a direction of flow of bleed gas G2 bled by the inner pipe 21 and that is directed toward the center of the flow of the bleed gas G2, wherein the discharge ports 25 discharge the cold air C in such a way as to satisfy the relationship that a ratio (MC/MG) of a momentum MC of the cold air C per discharge opening 25 to a momentum MG of the bleed gas G2 is 1.2 to 4.0, and the relationship that a value (m-1) obtained by dividing a ratio (VC/VG) of a wind speed VC of the cold air C to a wind speed VG of the bleed gas G2 by an inner diameter D of the inner pipe 21 is 1.5 to 3.5.
