Problems solved by technology
[0004] The experimental part of the supercritical water experimental device above all adopts electric heating, and the cost is relatively high, and the experimental part is in the form of a single channel or a double channel fixed, which cannot realize multi-purpose switching, and cannot study the flow heat transfer characteristics of the narrow channel natural circulation. Moreover, the cost of the above-mentioned experimental devices is extremely expensive, and it is difficult to meet the research needs of students

The invention discloses a supercritical water narrow-channel natural circulation experimental apparatus comprising a preheating portion, an experiment portion, a heat exchange portion, a pressure-stabilizing portion, and a water supply portion. The preheating portion, the experiment portion, and the heat exchange portion are connected successively via a main pipeline to form a closed loop. The pressure-stabilizing portion and the water supply portion are connected with the main pipeline of the closed loop. The preheating portion is an oil bath heating portion. The experiment portion a detachable experiment pipe. The heat exchange portion comprises a heat exchange water tank and a cooling water pump. The pressure-stabilizing portion comprises a pressure-stabilizing tank, a nitrogen cylinder, and an air bag in the pressure-stabilizing tank. The water supply tank comprises a deionized water tank, filter, and a plunger pump.
Description
technical field [0001] The invention relates to an experimental device in the field of thermal energy and nuclear energy, in particular to an experimental device for studying the heat transfer characteristics of supercritical water. Background technique [0002] The supercritical water-cooled reactor is the only water-cooled reactor among the six fourth-generation reactors selected internationally. Its heat utilization efficiency and simplified systems and equipment have shown very good potential economics. Compared with conventional pressurized water reactors, supercritical water reactors adopt a single-loop direct circulation design, and the working fluid at the outlet of the core directly enters the steam turbine without the need for steam generators and pressurizers. Compared with conventional boiling water reactors, supercritical water is a single-phase fluid, and there is no need to set up a steam-water separator and a dryer. For supercritical water-cooled reactors, t...
