摘要
In a flue gas denitrification process, in which a raw gas flue gas mass flow (121) flowing in a flue gas duct (120) of a boiler or steam generator (110) of a power plant (100) fired with a carbonaceous fuel is in one, in particular selective, flue gas exit side of the boiler or steam generator (110) catalytically operating flue gas denitrification reactor (210) is de-nitrogened, wherein flue gas exit side of the boiler or steam generator (110) and in the flue gas flow direction (R) upstream of the flue gas denitration reactor (210) by means of a reducing agent feed (240) reducing agent (221), in particular an ammonia or urea exhibiting Reducing agent (221), in the in the flue gas duct (120) flowing raw gas flue gas mass flow (121) is introduced and / or injected, a solution is to be created, which allows good mixing of flue gas and reducing agent resource-friendly, especially without zus This is achieved in that the reducing agent (221) as part of a preheated combustion air partial stream (231) in the in the flue gas duct (120) flowing raw gas flue gas mass flow (121) initiated and / or is injected, wherein the combustion air partial stream (231) from one or more Luftvorwärmeinheiten (130, 130 '), which in a boiler or steam generator (110) combustion air (141) supplying the combustion air duct (140) are arranged, or in the air flow direction (L ) is branched off downstream of said one or more Luftvorwärmeinheiten (130, 130 ') from a preheated combustion air stream (142).
