Abstract

PURPOSE:To obtain a suction piping for measuring the concentration of ammonia and nitrogen oxide accurately, by arranging a suction piping for measuring an exhaust gas inserted into a duct as double pipe to use a quartz tube as inner tube and a metal tube as outer tube. CONSTITUTION:A combustion exhaust gas 3 of a gas turbine 1 is discharged into an exhaust duct 2. Ammonia 4 discharged from an ammonia injector 5 is sprayed into the duct 2 and the exhaust gas 6 gives a gas composition containing ammonia and a low nitrogen oxide reduced. The exhaust gas 6 sucked with a suction piping 7 enters an analyzer 8 through a hose or the like outside the duct. The suction piping 7 made up of a metal tube 13 as outer tube and a quartz tube 12 as inner tube with no clearance therebetween. The quartz tube 12 as inner tube is so constructed that it is sliced into pieces to a proper length to pack. The tip of the outer tube 13 of the suction piping is bent so as not to let the inside quartz tube 12 drop.
