The invention provides a gas-assisted dual-fuel nozzle used for a chemical regenerative cycle. The gas-assisted dual-fuel nozzle comprises a pyrolysis gas channel outer wall, a pyrolysis gas channel inner wall and a main oil path inner wall. A pyrolysis gas channel is formed between the pyrolysis gas channel outer wall and the pyrolysis gas channel inner wall. A main oil path is formed between the pyrolysis gas channel inner wall and the main oil path inner wall. An auxiliary oil path is arranged in the main oil path inner wall. A spring and an auxiliary oil path swirler are mounted in the auxiliary oil path, wherein the spring abuts against the auxiliary oil path swirler to enable the auxiliary oil path swirler to be coaxial with the main oil path inner wall. A main oil path rotational flow groove is formed in the end portion of the main oil path. An outlet of the auxiliary oil path swirler is communicated with an outlet of the main oil path rotational flow groove. The cross section of the end portion of the
