This utility model discloses a liquid fuel combustion device with multiple oil channels and multiple ignition points. The combustion body consists of a base, a vaporization combustion cylinder, a cyclone air inlet cylinder, and an impeller air inlet channel. The base is provided with two or more oil inlets, which are evenly distributed along the circumference of the primary vaporization combustion chamber and are arranged along the tangent of the primary vaporization combustion chamber. Each oil inlet is provided with an ignition plug and an atomizing combustion net. Compared with the prior art, this embodiment can meet the needs of combustion devices with high fuel values ​​through the dual oil channel design, and does not require the use of an oil pump for pressurization.
