More specifically, the peripheral duct in the first mixer has its inlet in front of the outlet of the atomizing gas duct of the external device, and its outlet directed into the central duct in the first mixer itself. It is placed. The slope of the peripheral duct is 35° to the axis of the central duct
A second mixer, set in the range of ~65° and pressed against the front of the first mixer, has a chamber concentrically directed towards the outlet of the central duct and directs the atomized fuel to the outside. It consists of several passages for feeding into the firebox of the central duct, which are cut into the wall opposite the said outlet, the axis of each passage being at a distance of 200 to 200 mm with respect to the axis of the central duct.
It is tilted at an angle of less than 45 degrees.
