A test system for verifying the performance of steam generator steam-water separation device

Abstract

The invention discloses a test system for verifying the performance of a steam generator steam-water separation device, including a high-pressure superheated steam boiler system, a flow meter A, a superheated steam desuperheating and decompression device, a desuperheating water regulating valve, a flow meter B, and a mixer , flow meter D, circulating pump, flow meter C, regulating valve, atomization device, steam-water separator, dryer, test container, saturated steam temperature and pressure reduction device, condenser. The invention adopts the superheated steam of the superheated steam boiler as the steam source, the flow rate can be accurately measured, and the performance test of the steam generator steam-water separation device from low steam load to high steam load and extreme working conditions can be realized. The test parameters have good scalability and can be adjusted and controlled. flexible. A branch is drawn from the outlet of the circulating pump to adjust the humidity of the steam at the inlet of the dryer. This branch is connected with a water atomization device to meet the requirements of performance tests under different inlet humidity conditions of the dryer.

Description

technical field [0001] The invention relates to the technical field of steam generator tests, in particular to a test system for verifying the performance of a steam generator steam-water separation device. Background technique [0002] The saturated steam generator has been widely used in the pressurized water reactor nuclear power plant and is one of the key equipment of the system. It undertakes important functions such as parameter matching and operation follow-up of the primary and secondary circuits, normal core heat transfer and residual heat export, and radioactive material shielding. Its working performance and safety reliability directly affect the economy and safety of the entire nuclear power plant. [0003] The outlet steam humidity is one of the key indicators to measure the working performance of the saturated steam generator. In order to ensure that the humidity of the outlet steam meets the requirements of the operation index, a steam-water separation devi...
