| titleOfInvention | SCR (Selective Catalytic Reduction) flue gas denitration system for burning lignite |
| abstract | The invention discloses an SCR (Selective Catalytic Reduction) flue gas denitration system for burning lignite. After flue gas exhausted from a hearth passes through a horizontal flue, an economizer and a high-temperature air preheater and then is fully mixed with reductive ammonia water injected into an ammonia injection grid, the flue gas enters an SCR reactor and generates selective catalytic reduction reaction under the action of a catalyst, and the flue gas enters a low-temperature air preheater after reaction. During lignite burning, the flow of air in an air by-pass pipeline is regulated, so that high-temperature flue gas entering the SCR reactor can be cooled by air conveying to the hearth from a fan in the high-temperature air preheater to 320-400 DEG C needed by a denitration catalyst, and the denitration catalyst does not have a sintering risk at present. After the air supplied by the fan to the hearth is preheated through the low-temperature air preheater, the air is heated by the high-temperature flue gas in the high-temperature air preheater to the temperature range of over 400 DEG C needed by the lignite or lignite co-combustion. |
