Abstract

Способ для осуществления сжигания низкокалорийного горючего газа при помощи по меньшей мере одной горелки, содержащей наконечник на центральной оси (х), согласно которому создают смесь топливного газа и воздуха горения, вращающуюся вокруг центральной оси. Способ отличается тем, что содержит следующие этапы, на которых перед наконечником горелки нагнетают поток невоспламеняемой предварительной смеси, содержащей смесь воздуха предварительного смешивания и топливного газа, дополнительный поток для достижения порога воспламенения смеси перед наконечником горелки, при этом поток нагнетается в центр потока предварительной смеси в виде центрального дополнительного потока и/или вокруг потока предварительной смеси в виде периферийного дополнительного потока. Объектом настоящего изобретения являются также горелка, выполненная с возможностью осуществления способа, и установка для сжигания, использующая горелку.A method for burning low-calorie combustible gas using at least one burner containing a tip on the central axis (x), according to which a mixture of fuel gas and combustion air is rotated around a central axis. The method is characterized in that it comprises the following steps, in which a stream of non-flammable pre-mixture containing a mixture of pre-mixing air and fuel gas is injected in front of the tip of the burner, an additional stream is reached to reach the ignition threshold of the mixture in front of the tip of the burner, and the stream is pumped to the center of the stream of pre-mix in as a central additional stream and / or around the preliminary mixture stream in the form of a peripheral additional stream. The object of the present invention are also a burner configured to implement the method, and a combustion plant using a burner.
