Abstract

PROBLEM TO BE SOLVED: To continuously measure a temperature and a concentration of exhaust gas even in a high-temperature ambiance, by loosely fitting a heatproof pipe in a sensor main body, and supplying cool air into a furnace through a gap between the heatproof pipe and the sensor main body. SOLUTION: A heatproof pipe 13 is loosely fitted from a central part to a base end part of a water-cooled sensor main body 9. The heatproof pipe 13 is fixedly set to a furnace wall 2a. A cool air (b) is supplied into a secondary combustion furnace 2 through a gap 14 between the heatproof pipe 13 and the water-cooled sensor main body 9. Since the sensor main body 9 is cooled by the supplied cool air (b), a cool water (a) circulating in the main body 9 is prevented from boiling, and cooling efficiency from deteriorating. A temperature can be continuously measured by an R thermocouple 11 inserted into a penetrating pipe 9B. The heatproof pipe 13 is preferably formed of ceramic. The heatproof pipe 13 is resistive to damage and deterioration by a high- temperature ambiance, and therefore the temperature and a concentration of exhaust gas can be measured for a further longer time continuously.
