从设备的本发明进行用于以预定的空气比调节燃烧空气流（1）要被操作的大气燃料气体消耗装置（2）与燃烧室（3）。 的基本结构包括用于流动横截面（5）和用于燃料气体消费者供给燃料气体流（7）的管道（6）的调节元件（4）（2）。 在调节部件（4）与来自燃烧空气流（1）产生的力相接合。 此外，燃料气体压力调节装置（8）被提供给线（6），用于提供（7）连接所述燃料气体流。 到的燃烧气体压力调节装置（8）的定位驱动器（9）连接，它设置调节元件（4），以预定的空气比率。 在该装置中，燃烧用空气流量可以正比于燃料气体流量被改变，以这样的方式使空气比所有操作条件下保持足够恒定的。

The invention relates to a device for adjusting the combustion air flow (1) at a predetermined air ratio to be operated atmospheric combustion gas consumers (2) with the combustion chamber (3). The basic structure includes an adjustment element (4) for a flow cross-section (5) and a conduit (6) for supplying a fuel gas stream (7) for fuel gas consumer (2). On the adjusting element (4) is engaged by a force resulting from the combustion air stream (1). In addition, a fuel gas pressure adjustment device (8) is provided, which is connected to the line (6) connected for supplying the fuel gas stream (7). To the combustion gas pressure adjustment device (8) a positioning drive (9) is connected, which sets the setting element (4) to the predetermined air ratio. With this apparatus, the combustion air flow rate may be changed in proportion to the fuel gas flow rate, in such a way that the air speed is kept sufficiently constant under all operating conditions.
