Definitions
- the invention relates to the field of high pressure injectors, intended for injecting water into a machine or an installation comprising a pressure tank.
- the latter consists of the steam production balloon of a steam boiler. This is the case, in particular, of steam generators used in nuclear reactors, in particular pressurized water.
- the use of such an injector could be made for all types of tanks producing steam by using part of this steam as a source of motive energy and a low-pressure tank as a source of water.
- the principle of a steam injector is to expand steam under pressure in a narrowing followed by a divergent 2, for example a Laval nozzle, to reach a speed at the outlet thereof. supersonic and pressures which may be lower than atmospheric pressure.
- a water inlet is arranged by an annular intake chamber 3.
- the low pressures make it possible to suck up the water coming from the intake chamber 3, then the steam gives up its energy to the water by condensing.
- the mixing chamber 4 is generally conical in shape and converges towards a neck 5. At this point, the water reaches its maximum speed.
- the object of the invention is therefore to remedy these drawbacks by proposing a steam injector which can be used in pressurized water reactors and which can inject water up to pressures of around 80 bars.
- the main object of the invention is a high pressure steam injector, comprising:
- an axial drain consisting of a sampling duct is placed in the middle of the neck in order to reduce the section of the neck and take a part of the vapor which has not been condensed and evacuate it towards the outside. It has indeed been shown that the flow remains essentially annular up to the neck.
- the drain In order to be able to use the drain temporarily or to vary the minimum passage section, it can be mounted movable longitudinally, so that it can be moved relative to the neck.
- the first part of the axial drain is in a conical shape in which the sampling holes are made, in order to allow progressive drainage of the vapor.
- the injector according to the invention incorporates the main elements of the steam injector, according to the prior art, and described with reference to FIG. 1, with the exception of the lateral sampling drain 6
- a steam inlet 1 opening into a Laval nozzle 2
- an annular inlet chamber 3 opening into the mixing chamber 4, placed at the outlet of the nozzle 2 and ending in the neck 5.
- a diffuser 7 opening into an outlet 8.
- an axial drain 10 is inserted, consisting of a sampling conduit and extending through the diffuser 7 to terminate outside 9 , apart from the steam injector which is the subject of this application.
- the axial drain 10 also makes it possible to reduce the flow passage section at the neck 5, between the mixing chamber 4 and the diffuser 7, and therefore thus increase the maximum pressure of the flow towards the outlet 8, compared to the case where such an axial drain would not be used with the same diffuser. It is assumed that the increase in pressure is practically inversely proportional to the cross-section at the level of the neck 5.
- the axial drain 10 is also used for starting the steam injector. Indeed, in this case, the steam inlet 1 is closed and the water supply is open, that is to say that it circulates in the annular intake chamber 3 and arrives in the mixture 4. All or part of this water is discharged through the axial drain 10 to the outside, according to the design of the discharge downstream of the outlet 8.
- the steam inlet 1 is open, strong condensation occurs in the mixing chamber 4.
- the pressure in this mixing chamber 4 then drops until it reaches its nominal value.
- the flow of the flow then becomes supersonic at the outlet of the nozzle 2.
- the central flow initially in the state liquid, becomes vapor and is captured by the axial drain 10.
- the flow of water passes annularly against the walls of the neck 5 and extends into the diffuser 7.
- this can be of variable section.
- the axial drain 10 could have a diameter increasing appreciably as it develops in the diffuser 7, starting from the neck 5.
- this drain axial 10 can enter the mixing chamber 4 to ensure the withdrawal of steam, more gradually.
- the first part of the drain could then be of conical shape 11 with a sufficient number of sampling holes.
- the axial drain 10 can be movable longitudinally along the axis of the steam injector according to the invention and can therefore be introduced and removed.
- it can be removed downstream from the neck 5, that is to say in the diffuser 7, when the steam injector is started. It can be replaced in the neck 5, once the speed of the steam injector has been established, and resume its function of withdrawing steam and reducing the flow passage section in the neck 5.
- a first use of the steam injection is provided for supplying water to a steam generator 16 of a pressurized water reactor.
- the steam injector 13 is used to inject water into this steam generator 16, using the energy of the steam generated by the latter.
- a low pressure water reservoir 17 supplies the inlet chamber of the injector 13, via a supply valve 22 which is therefore closed when the steam injector 13 is stopped. The latter is therefore at ambient pressure.
- the axial drain 10 is open and the steam injector 13 can be purged with water or steam.
- An outlet and purge valve 23 is placed downstream of the injector 13 and also closed.
- the water supply 22 and purge outlet 23 valves are then open and the flow of cold water is then carried out, by gravity, inside the steam injector 13 and exits through the axial drain 10 and the outlet and purge valve 23, the injector being lower than the water tank 17.
- the steam inlet valve 21, placed upstream of the steam injector 13, is opened up to a flow rate of several kg / s depending on the pressure of the steam.
- the condensation in the mixing chamber 4 on the previously obtained cold water flow allows the starting of the steam injector 13.
- the outlet and purge valve 23 is then closed, the first part of the outlet pipe 18 rises in pressure until the sudden rise of pressure in the diffuser 7.
- the valve 15 opens and the system has then reached its nominal operation.
- the water drawn from the reservoir 17 is injected into the steam generator 16, at a rate of 5 to 20 kg / s, depending on the water requirement of the latter, this being obtained by adjusting the supply valve by water 22.
- the system is stopped by closing the steam supply valve 21, followed by closing the water supply valve 22.
- the water supply valve 22 can be placed on the outlet line of the axial drain 10, that is to say towards the outside, referenced 9. It is so easy to provide a system water filling. Start-up is then carried out under the same conditions as the basic configuration.
