Description
Technical field
The present invention relates to liquid metal technical field of heating, and in particular to a kind of direct-type liquid metal sodium high power heating
System and heating means.
Background technique
Sodium-cooled fast reactor generallys use sodium-sodium-water circuit design, and sodium-steam generator is secondary circuit and three circuits
Important pivot, the main water supply of the heat that it generates reactor generates steam, so that pushing turbine does work.Steam hair simultaneously
Raw device still separates the important barrier in secondary circuit and three circuits, once heat transfer tracheal rupture will cause serious sodium-water reaction, makes
At serious safety accident, nuclear power station reliability of operation is influenced.A large amount of literature survey discovery, in the research and steaming of sodium-cooled fast reactor
In the test of vapour generator, the relatively early several country's heat that surrogate response heap exports in the way of gas heating for developing fast reactor
Amount.Wherein, India SGTF (Steam Generator Test Facility) rack power is 5.5MW, using gas heating.
Japanese SGTF (Steam Generator Test Facility) rack power is 50MW, by 1/5 power designs of Manjusri's heap.Lotus
Blue SCTF (Sodium Component Test Facility for testing of steam generator) test-bed
Power is 50MW, fired heater power 58MW.Flame heating method introduces simultaneously there are the matching of boiler and processing problems
Boiler increases a large amount of uncertainties in operation and safety, improves the level of empirical risk assessment, and it is great to increase generation
The probability of accident.
According to existing experiment operating experience, the Electric heating of sodium working medium can be divided into two major classes: radiant type heating and directly
Formula heating.Radiant type heating is to separate liquid metal sodium and heating rod, and sodium flows in independent sodium channel, by logical in sodium
For sodium radiation heat transfer of the heating rod being evenly arranged outside road into channel to provide heat, this heating method avoids sodium and heating
The direct contact of stick, but the thermal efficiency for penetrating heat exchange is lower, simultaneously because the design of radiation heat transfer needs, it can not be by heater body
Product is compact to design, causes entire heater volume larger.Direct-type heating is that heating rod is inserted directly into heating container, passes through sodium
Heat is transmitted with the heat convection on heating rod surface, directly, thermal loss is small for this heating method design, but heating rod and sodium hold
Device cylinder junction needs to weld, and causes weld seam quantity more, and which increase the design requirements to sodium shell.
