Apparatus for discharging sprays or mists, comprising an oscillating fire burner, and mist pipe for such an apparatus

An apparatus for discharging a mist material, comprising:

• an oscillating fire burner;
• a resonator connected to the oscillating fire burner;
• a supply line for mist material opening into the resonator;
• a mist pipe comprising a first pipe, wherein the resonator extends into the first pipe of the mist pipe;
• wherein the mist pipe further comprises a second pipe, a third pipe, and a fourth pipe, wherein the first, second, third and fourth pipes overlap one another at least partially so as to define a first annular passage between the first and second pipes, a second annular passage between the second and third pipes, and a third annular passage between the third and fourth pipes;
• wherein the second pipe comprises at least one suction opening for larger mist material droplets contained within the second annular passage.

• a mist pipe comprising a first pipe, wherein the resonator extends into the first pipe of the mist pipe;
• wherein the mist pipe further comprises a second pipe, a third pipe, and a fourth pipe, wherein the first, second, third and fourth pipes overlap one another at least partially so as to define a first annular passage between the first and second pipes, a second annular passage between the second and third pipes, and a third annular passage between the third and fourth pipes;
• wherein between the first pipe and the resonator a fourth annular passage is formed that is in flow communication with an annular space through which cooling air flows about the resonator, wherein a width of an annular gap of the fourth annular passage is smaller than a width of an annular gap of the first annular passage.
