    Abstract: Disclosed is a urea solution reformer and an exhaust gas purifier using the same, configured to heat a carrier gas supplied from a carrier gas source by a carrier gas heating unit (16), to inject the carrier gas heated by the carrier gas heating unit from a carrier gas injecting nozzle (17), and to cause a urea solution (18) to be supplied by a first urea solution supply nozzle (21) to a tip end of the carrier gas injecting nozzle so that the urea solution is atomized by the carrier gas injected from the carrier gas injecting nozzle. Provided to face toward the carrier gas injecting nozzle is a catalyst unit (23) for decomposing the atomized urea solution to reform it into an ammonia gas. Further provided is an ammonia gas supply nozzle (24) attached to an exhaust pipe (12) of an engine so as to supply the ammonia gas discharged from an outlet of the catalyst unit into the exhaust pipe. The urea solution is sufficiently atomized, and thus reformed into an ammonia gas by the catalyst unit with a good efficiency.
