Zusammenfassung:The invention discloses a heavy-duty gas turbine combustion chamber flame tube space size detection device and method, the position of a flame tube inlet is designed according to the standard value of a drawing, a self-centering expansion mechanism is installed at the flame tube inlet, and the flame tube inlet can be detected according to whether a standard disc installed at the flame tube outlet can pass through the inner ring of the flame tube outlet or not. The center of the disc is concentric with the center of the flame tube inlet expansion mechanism, and the outer diameter of the disc is obtained by subtracting the coaxiality tolerance from the diameter of the flame tube outlet. According to the method, the problem that coaxiality judgment is influenced by factors such as roundness and diameter tolerance when a three-coordinate measuring machine is used for detecting the thin-walled parts at inlets and outlets can be avoided, and meanwhile, the flame tube detection efficiency is improved by more than 60
