The invention relates to a dual-output atomizer, which comprises a body, a splitter vane, an atomizer A and an atomizer B, wherein the splitter vane, the atomizer A and the atomizer B are sequentially propped against the body and are sheathed and fixed by an end cover; the body is cylindrical, and a channel A and a channel B are formed at the center; one side of the splitter vane is propped against the body, for corresponding to the channel A and the channel B of the body, an inner circle of through holes and an outer circle of through holes are formed on the splitter vane; an annular oil balancing groove and a spin chamber, as well as a tangential groove around the spin chamber are formed on the side surface of the atomizer A, which is propped against the splitter vane; third oil inlet holes are arranged on the outer side of the annular oil balancing groove along the circumference of the atomizer A; a spin chamber corresponding to the spin chamber of the atomizer A is arranged on theside surface of the atomizer B, which is propped against the atomizer A, and the tangential groove is further arranged around the spin chambers; and a horn-shaped spout, which is communicated with the spin chamber and inwards concave, is arranged on the other side surface of the atomizer B. The two atomizers using a same set of program and mechanism used for controlling advance and retreat can simultaneously perform advance and retreat, and a variety of energy can be accurately and timely supplied under complex and emergency working conditions, thereby meeting complex combustion requirements of energy supply under the different working conditions.
