baffle air
Explanation:
The 'Blende' is called a baffle in English in this context, and the air emerging from the baffle is 'baffle air'.

sample refs:

A baffle-plate unit (11) comprises a baffle plate (13) and a carrier (18) for the baffle plate. …

Die Figuren 1 bis 5 zeigen eine erfindungsgemässe Blendeneinheit 11, welche aus einer Blende 13 und einem Blendenträger 18 mit zwei identischen Seitenteilen 15 und einem U-förmigen Bügel 17 besteht.

The gas stream flows forward axially of the burner and now comprising of fuel, air and waste gases is now allowed to expand within the area 18 of the liner 12 and intersect with a tangential flow of combustion air 9 (from the inlet 19) close to the exit into the furnace chamber near the baffle plate 5. The combustible mixture now further mixes on the perimeter of this stream with staged combustion air 8, on the upstream side of baffle plate 5, rotating the outer section of the stream 9. The baffle air will flow at up to about 40 m/s for cold air and up to about 300 m/s for heated air. In other words the partially reacting air/fuel/waste gas mixture is directed through an aperture in an air distribution baffle where the balance of the air required for complete combustion is delivered at high velocity. The remaining combustible mixture enters the furnace chamber at the burner baffle plate hot face and there expands and further proceeds to visibly burn local to the baffle air combustion streams 7. The resulting mixing of the fuel mixture with the balance of combustion air enables combustion to be completed within the confines of the retention quarl and furnace volume in an essentially flameless manner.

The velocity of the air streams exiting the baffle plate 5 induce waste gases into and so diluting the combustion air. Complete combustion does not occur until an equilibrium of velocities and mixture is achieved some way into the furnace chamber when flameless combustion 30 (Figure 6) takes place.

  -> If you mean the second reference text, that's partly because it's patent language and partly because the English is occasionally substandard.
