SAMPLING PROBE, INSTALLATION STRUCTURE THEREFOR, AND CEMENT PRODUCTION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a sampling probe capable of removing efficiently dust with a reduced spray amount, when collecting combustion exhaust gas in a kiln tail part of a cement kiln. SOLUTION: This sampling probe is provided with a tubular probe body 3 having a suction port 5 for the combustion exhaust gas, in its tip, and a spray mechanism 4 for spraying water from an inside of the probe body 3 toward the suction port 5. The probe body 3 has a space S for removing the dust between the suction port 5 and a nozzle 12 of the spray mechanism. The dust contained in the combustion exhaust gas is removed by the spray from the nozzle 12, in a process where the combustion exhaust gas flowing from the suction port 5 into the probe body 3 is passed through the space S.
