METHOD FOR DETECTING THE HOLE OF A RADIANT TUBE BY USING A TDSL APPARATUS, WHICH CAN REDUCE AN OPERATION TIME AND TO PREVENT THE LEAKAGE OF COMBUSTION GAS

摘要

PURPOSE: A method for detecting the hole of a radiant tube by using a TDSL apparatus is provided to detect a broken part of a radiant tube by heating a steel sheet with radiant heat.;CONSTITUTION: A method for detecting the hole of a radiant tube by using a TDSL apparatus comprises: a step of producing the laser of the wavelength absorbed from a TDLS apparatus into moisture or CO2; a step of passing the laser through the inside of the heated chamber with a plurality of radiant tubes(10) installed by discharging the laser through a mail out log(30) arranged in one side of a heated chamber; a step of receiving the optical signal through a receiver(40) arranged on the other side of the heated chamber after passing through the internal space of the heated chamber; and a step of analyzing a spectrum from the received optical signal.;COPYRIGHT KIPO 2010
