The invention discloses a test verification method and system for fuel nozzle modification, and belongs to the technical field of gas turbine tests. According to the test verification method and system, the reference performance of a single-tube combustion chamber using a fuel nozzle for burning liquid fuel is used as the reference and is compared with the combustion performance of single-tube combustion chambers with natural gas fuel nozzles with different sizes for burning natural gas, and a natural gas nozzle is preferably selected. Deviation in nozzle modification design and manufacturing is corrected by applying test results, so that the feasibility of changing a gas turbine from a fuel oil nozzle taking fuel oil as fuel to a natural gas nozzle taking fuel gas as fuel is proved. According to the method, the nozzle modification design is corrected through test data, and it is guaranteed that the natural gas nozzle can meet the overall requirement of the gas turbine. The method can also be widely applied t
