PURPOSE: A gas sensing device of tap holes of a furnace is provided to efficiently sense gas of high temperatures discharged from tap holes of a furnace, thereby confirming the existence of a gas leakage. CONSTITUTION: A gas sensing device of tap holes of a furnace comprises a collector(110), a filter(120), a cooling chamber(130), a pressure control valve(140), a flow rate control valve(150), a detection sensor(160), a suction unit(170), and a cooling pipe(181). The collector is arranged to be closed to tap holes of a furnace, thereby colleting sample gas. The filter filters foreign materials from the gas has flown through the collector. The cooling chamber cools the sample gas filtered by the filter. The pressure control valve controls pressure of the sample gas cooled by the cooling chamber. The flow rate control valve controls a flow rate of the sample gas in which the pressure is controlled by the pressure control valve. The detection sensor detects components of the sample gas in which the flow rate is controlled by the flow rate control valve. The suction unit sucks outside air supplied from an air supply unit(190) and the sample gas has passed through the detection sensor, thereby moving. The cooling pipe guides mixed gas mixed in the suction unit to the cooling chamber. |
