| titleOfInvention | Method and apparatus for removing nitrogen oxides in exhaust gas |
| abstract | PURPOSE: To efficiently remove NOx in combustion exhaust gas by gasifying a solid granular or powder material of sublimability and gasifiability as a reducing agent and supplying the gasified material to the exhaust gas. n CONSTITUTION: When NOx are directly reacted with a reducing agent such as urea at high temp. in the absence of catalyst, combustion exhaust gas 1 is introduced into urea evaporator 2 and solid urea 3 is gasified by heating. Gas 1 is then fed to reactor 4 kept at high temp. together with gaseous urea molecules to carry out denitration, and the denitrated gas is introduced into exhaust line 5. At this time, the urea is gasified at 100W420°C and injected into the exhaust gas. In case of catalytic reduction using catalyst, gas 1 is introduced into evaporator 2 and urea 3 is gasified by heating. Gas 1 is then fed to catalyst-packed reactor 6 together with gaseous urea molecules to complete denitration, and the denitrated gas is introduced into line 5. By these methods, NOx in exhaust gas can be removed at reduced construction and operational costs. n COPYRIGHT: (C)1979,JPO&Japio |
