The utility model discloses a dual-fuel fuel oil range comprising a range body, a burner in the range body and a dimethyl ether synthesizer. The dimethyl ether synthesizer is communicated with the combustible gas inlet of the burner. An aluminium oxide wire is arranged in the dimethyl ether synthesizer. The dual-fuel fuel oil range adopts the mixed fuel of dimethyl ether and methanol to make up the defects of methanol liquid fuel, such as low cetane number, large gasification potential heat and difficult ignition compared with gas fuel. The adoption of the mixed fuel of dimethyl ether and methanol, having high cetane number, improves the ignition properties of the fuel. In addition, no electricity is needed for heating during the ignition, and no air pump is needed for pressurization during the delivery. The safety is improved.
