Beschreibung
Zusammenfassung:	An apparatus for reducing NOx in exhaust gas is provided to increase the endurance of an exhaust pipe by preventing moisture from being generated in the wall of the exhaust pipe through allowing urea to be injected through a vaporization chamber. An apparatus for reducing NOx in exhaust gas comprises an exhaust pipe(300), through which exhaust gas passes and a nozzle(310) through which urea is introduced into the exhaust pipe. A catalytic section(430) includes a reduction catalytic layer(320) that facilitates reaction between the urea injected from the nozzle and NOx. The nozzle passes through a vaporization chamber(330) in which the urea is vaporized. The vaporization chamber includes an injector(340), which injects the urea into the vaporization chamber, a heating wire(350), which heats the urea injected from the injector, and a housing(360) having a hole such that the urea is introduced into the nozzle.
