Abstract

Предложен способ снижения выбросов вредных газов из котла (1), работающего на газообразном топливе, который содержит уплотненную камеру (2) сгорания с принудительной тягой, в которой есть горелка (3), к которой подведен первый трубопровод (5) для втягивания воздуха (A) для горения и от которой отходит второй трубопровод (6) для выпуска топочных газов (F) горения. Предусматривают втягивание части топочных газов или отходящих газов из второго трубопровода (6) и их введение в воздух (A) для горения, чтобы уменьшить процентную долю атмосферного кислорода, присутствующего в этом воздухе (A) для горения, а затем уменьшить образование вредных газов в топочных газах (F) горения. Также заявляется котел, эксплуатируемый в соответствии с вышеупомянутым способом.A method is proposed for reducing emissions of harmful gases from a boiler (1) operating on gaseous fuel, which contains a compacted combustion chamber (2) with a forced draft, in which there is a burner (3) to which the first pipeline (5) is connected to draw in air (A ) for combustion and from which the second pipeline (6) departs for the release of flue gases (F) of combustion. A part of the flue gases or off-gases from the second pipeline (6) is introduced and introduced into the air (A) for combustion in order to reduce the percentage of atmospheric oxygen present in this air (A) for combustion, and then reduce the formation of harmful gases in the flue gas. gas (f) burning. Also claimed is a boiler operated in accordance with the above method.
