(1) interior liquid fuel evaporation is sprayed by the aperture of spray head with holes (3), and with level-one rotational flow gas in level-one inlet plate and its
Mixing and combustion zone are formed between the metal tube and center fuel metal tube (1) of metal tube integrated apparatus (4) right end, are generated steady
Fixed swirl flame；Drive end bearing bracket is close on the outside of the metal tube of level-one inlet plate and its metal tube integrated apparatus (4) left end
(8), secondary inlet plate (9) and rear end cap (10), gas flow through secondary inlet plate (9) and are formed afterwards by the second swirl-flow devices (6)
Second level rotational flow gas, and near the metal tube lower exit of level-one inlet plate and its right end of metal tube integrated apparatus (4)
It is mixed with unburned fuel, single-stage combustion area product and forms intermediate zone；Wherein I and II rotational flow gas is oppositely oriented,
The swirling number of outside second level eddy flow is higher than the swirling number of internal level-one eddy flow, and second level eddy flow oxidizer flow rate is revolved greater than level-one
Flow oxidizer flow rate；Center fuel metal tube (1) one end has screw thread, facilitates and adjusts spray head and metal tube with holes to axial
Position is conducive to be suitable for the liquid fuel with different combustion characteristics.
2. a kind of classification derotation air-flow as described in claim 1 promotes the burner of liquid fuel combustion evaporation, feature exists
In: the cavity is provided with bead.
3. a kind of classification derotation air-flow as claimed in claim 2 promotes the burner of liquid fuel combustion evaporation, feature exists
In: the bead is steel ball.
