ていない点にある。Certain known liquid fuel atomizers utilize a modest energy exchange between the fuel and the atomizing gas, such as those known as "Y-jet" atomizers and known as fuel "internal mixing" atomizers. can be done. However, the disadvantage of these atomizers is that they are not suitable for atomizing highly viscous liquid fuels.

４５゜以内の角度で傾いている。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.

にある。The advantage of the fuel injection unit according to the present invention is that the fuel is mixed with high exchange energy in the first mixer and then mixed with low exchange energy in the second mixer, so that the blown fuel is very easily atomized. The fuel burns permanently in the boiler's firebox, and its combustion efficiency is extremely high.
