- 摘要：
PROBLEM TO BE SOLVED: To adequately atomize a urea solution, and to thereby efficiently reform the urea solution into ammonia gas by a catalyst section.
SOLUTION: A carrier gas supplied from a carrier gas source is heated by a carrier gas heating section 16, the carrier gas heated by the carrier gas heating section 16 is injected from a carrier gas injection nozzle 17, and a urea solution 18 is supplied to the tip of the carrier gas injection nozzle by a first urea solution supply nozzle 21 so that the urea solution 18 is atomized by the carrier gas injected from the carrier gas injection nozzle 17. A catalyst section 23 for decomposing the atomized urea solution 18 and reforming the solution into ammonia gas is provided facing the carrier gas injection nozzle 17. Further, an ammonia gas supply nozzle 24 for supplying to an engine exhaust pipe 12 the ammonia gas discharged from an outlet of the catalyst section 23 is attached to the exhaust pipe 12.
