Embodiment

[0018] Such as figure 1 As shown, the present invention is a steam generator feed water temperature control simulation system, the main feed water pipe of the steam generator is connected with the main feed water pump 1 and the secondary side inlet 10 of the steam generator, and is divided into two parallel branches in the middle, one flow After passing through the regenerator 2, the fluid is heated by the steam on the other primary side of the regenerator 2, and then merges with the fluid of another branch, that is, the feedwater bypass, and flows to the secondary side inlet 10 of the steam generator; the feedwater bypass is installed on the feedwater bypass The flow regulating valve 3 is used to adjust the flow rate of the feed water bypass, and the heat exchange temperature measuring device 4 is installed on the outlet pipe of the regenerator 2 to measure the temperature of the feed water coming out of the regenerator 2. The inlet temperature measuring device 5 is installed...

Abstract

The invention discloses a steam generator feedwater temperature control simulation system. The main feedwater pipeline between the main feedwater pump and the secondary side inlet of the steam generator passes through a regenerator, and the secondary side outlet of the steam generator is connected with two Parallel branch pipelines, one of which is connected to the condenser after passing through the steam flow regulating valve of the main steam pipeline, and the other branch is connected to the condenser after passing through the steam bypass stop valve, the steam bypass flow regulating valve and the regenerator in sequence . The present invention can use the high-temperature steam generated by the steam generator as a heating source to preheat the feed water entering the steam generator, eliminate the energy consumption caused by preheating by an additional power supply, and improve the energy utilization rate of the test device. Output high-temperature steam preheating can realize feedwater temperature control with a large flow rate variation range. At the same time, the combination of steam bypass regulation and feedwater bypass regulation can realize the regulation of steam generator feedwater temperature quickly, efficiently and accurately.

Description

technical field [0001] The invention relates to the field of test and research equipment related to a nuclear reactor secondary loop system, in particular to a steam generator feed water temperature control simulation system. Background technique [0002] With the development of nuclear energy technology, nuclear reactor technology has gone through three generations. The current mainstream reactor technology is the third-generation nuclear reactor technology. All countries are currently developing fourth-generation nuclear reactors and other new nuclear reactors, such as modular small reactors. For the research and development of each new type of reactor, it is necessary to conduct experiments to verify the steady state and transient design parameters of this type of reactor, especially the operating characteristics of the steam generator during the steady state and transient state. When studying the operating performance of steam generators, it is necessary to conduct exper...
