Abstract

PURPOSE: To maintain a high denitration capacity and to reduce the NOx concentration of combustion gas to be used for a heat source in a waste-heat collecting boiler using the combustion gas from a gas turbine for the heat source.
CONSTITUTION: In a waste-heat collecting boiler 20, the exhaust gas of 370 degrees C conducted from a gas turbine 10 is mixed with the ammonia gas sprayed from an ammonia injecting nozzle 22 of a denitrating device 30 provided in the upper stream side of a heater 21, and is then conducted into a reactor 31, where nitric oxide is removed by the reducing resolution process of a catalyzer. Subsequently, the exhaust gas is made to flow down to the heater 21 and others in the downstream. In this construction, a highly efficient denitrating device can be added only by changing the arrangement of ducts in a waste-heat collecting boiler device
