The invention aims to provide a dual-fuel spray nozzle for oil-gas automatic switching in chemical heat return circulation, and the spray nozzle comprises a gas pipeline, a fuel pipeline and a gas circuit inlet fuel pipeline component; the gas circuit inlet fuel pipeline component is arranged outside the fuel pipeline and is arranged in the gas pipeline; the end of the gas pipeline is provided with a gas cyclone spout; the end of the fuel pipeline is provided with a fuel cyclonic chute spout; and the fuel cyclonic chute spout is arranged in the center of the gas cyclone spout. According to the dual-fuel spray nozzle for oil-gas automatic switching in the chemical heat return circulation, the distribution of pyrolysis gas in a combustion chamber is uniform, and no extremely oxygendeficient or oxygen-enriched area exists. The fuel and the pyrolysis gas are switched conveniently, and the adaptability and the reliability of a combustion engine during a fuel switching process are improved. Compared with a traditio
