The invention provides a non-intrusive gas turbine fuel gas temperature measuring device and method. The non-intrusive gas turbine fuel gas temperature measuring device comprises a plurality of temperature sensors, a signal collecting and processing controller and an axially movable support. Under the control of the axially movable bracket, the temperature sensor and the signal acquisition and processing controller are arranged at different axial positions to obtain the temperature data of the outer surface of the gas turbine with different axial sections, and then a comparison curve of the temperature data of the outer surface of the casing and the gas temperature data of the gas turbine on the test bed is obtained; performing statistics on a curve that the temperature of the outer surface of the casing changes along with the gas temperature in the gas turbine by utilizing linear fitting to obtain a corresponding coefficient matrix of different measuring points at different axial positions; and multiplying t
