Abstract: Disclosed are a test loop for simulating a steam generator with or without an axial economizer and a test method thereof. The loop includes a cooling water loop, a water supply loop, a recirculated water loop and a power supply. The cooling water loop is used for condensing and cooling wet steam and providing the wet steam to the water supply loop and the recirculated water loop. The water supply loop is used for providing cold-state water supply for a test device, the recirculated water loop is used for reheating cooled water to be saturated and providing the water to the test device. The power supply is used for supplying power to heating equipment and an electric heater in the test device. The present disclosure provides a test method of the loop. Simulation tests can be carried out on a steam generator with or without an axial economizer.
