Flue gas denitration device and operation method thereof |
| abstract |
[Problem] To reduce exhaust water droplets relatively quickly even under conditions of low exhaust gas temperature at low load, and to completely exhaust NH 3 before reaching the denitration catalyst layer To provide a denitration device and its operation method. SOLUTION: A economizer 1 for recovering heat of boiler combustion exhaust gas and a denitration reactor 3 are sequentially provided in the exhaust gas flow path, and the denitration inlet on the upstream side of the denitration reactor 3 bypasses the economizer 1 and exhausts the exhaust gas. A bypass duct 5 having an open / close damper 6 leading to the duct 2 is provided, and urea water is sprayed in the denitration inlet duct 2 in or near the guide duct 11 provided in the denitration inlet duct 2 for introducing exhaust gas from the duct 5. This is a flue gas denitration device provided with a nozzle 8. When the exhaust gas temperature at the time of boiler low load is low, the exhaust gas is put into the guide duct 11 from the bypass duct 5 and sprayed with urea water here can sufficiently maintain the temperature condition for generating NH 3 .
