Document Type and Number:
WIPO Patent Application WO/2017/110292
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a denitrator that can further improve denitration efficiency even when a nozzle is set in a space in an area with normal exhaust gas at 1000°C or greater directly after combustion in a combustion furnace. The present invention provides a denitrator 1 that eliminates NOx in exhaust gas generated by a combustion furnace 2 by infusing a reducing agent and is characterized by: having, installed above the combustion furnace 2, a housing 3 that is provided with a discharge opening 5 for exhaust gas in one end 3a and is formed in a shape wherein the flow cross-section gradually widens toward the discharge opening 5; and infusing the reducing agent on the other end 3e side of the housing 3 while collecting the exhaust gas and introducing the same to the discharge opening 5 by means of the housing 3.
