Structure, function and the technical characterictic of each major part of apparatus of the present invention (parts) are as follows:
(1) water system
The medium that this device takes place as water vapour with the deionized water in the water butt 12.In order to simulate the situation of power plant truly, select for use the Ar gas of degree of depth deoxidation that deionized water is carried out deoxygenation, so that dissolved oxygen concentration is reduced to below the 1ppm.With the deionized water ebuillition of heated after the deoxygenation, the water vapour of generation is introduced in the reaction chamber.(oxygen level of water vapour is less than 1ppm in order to satisfy the desired technical parameter of test, maximum water vapour generating capacity is greater than 1L water/h, the setting deoxygenation time is not less than 20h), water system has adopted the moisturizing drum 37 and the moisturizing keg 34 of a constant volume, can satisfy moisturizing keg 34 provides deaerated water more than the 20h continuously for water vapour generating means (there-necked flask 31 that has electric jacket 30), guarantees that simultaneously finishing deoxygenation for moisturizing drum 37 during this period handles.Changeable water supply controller 35 links to each other with solenoid valve 36, in order to the water level in the control moisturizing keg 34.When water level reduced, solenoid valve 36 was opened, and moisturizing drum 37 injects deaerated water in moisturizing keg 34.
In order to supply water according to the size of water vapour generating capacity in the water vapour generating means, selected water level controller 29 for use, come the switching of control electromagnetic valve 33 by the variation of liquid level, thereby realize controlling automatically the water supply of moisturizing keg 34 and water vapour generating means.
The operating process of water system is: the deionized water that makes is injected moisturizing drum 37 with water pump 3, close the ball valve 5 on the water injecting pipeline after filling with.Adopt high-purity Ar gas inflation deoxygenation 20h, inject moisturizing keg 34 after finishing deoxygenation, the water supply steam raising plant uses.
(2) air-channel system
Steady, controlled for the flow velocity that makes Ar gas in the gas circuit, pressure maintaining valve 9, flow stabilizing valve 8 and flowmeter 7 have been installed in the air-channel system of Ar gas cylinder 4.Adopt 10 pairs of Ar gas of pyrogallic acid solution to carry out degree of depth deoxidation, further carry out flow control by stop valve 11, the Ar gas after deoxidation finishes can be discharged through flashback tank 12 by stop valve 13.In order as early as possible the air in reaction chamber 21 and the water vapour generating means to be discharged, a vacuum pump 16 has been installed in this gas circuit.When bleeding stop valve 18 and stop valve 25 are closed, stop valve 32 and stop valve 19 are opened.After gas is discharged fully, vacuum pump 16 and stop valve 17 are closed.
Ar gas also has another effect in this test.Because water system is airtight, when moisturizing keg 34 constantly supplies water for the water vapour generating means, pressure in the bucket constantly reduces, and the water vapour generating means causes its inside slightly to be malleation because of constantly producing water vapour, so just normal water supply can't be realized, thereby Ar gas will be fed all the time in the moisturizing keg 34.Because the Ar gas that feeds needs to discharge from moisturizing keg 34 continuously, therefore in bucket, feed all the time under the situation of Ar gas and can not guarantee normal water supply.In order between delivery period, to keep pressure in the bucket to be higher than pressure in the water vapour generating means, install a solenoid valve 14 additional in the outlet side of moisturizing keg 34, negative-phase relay control by the changeable water supply controller 35 that links to each other with solenoid valve 36, when supplying water for the water vapour generating means, automatically close the solenoid valve 14 of moisturizing keg 34 outlet sides, make to keep malleation in the bucket.

(3) water vapour generation systems
As thermal source, its rated power is 450～1100W with electric jacket 30, and voltage is 0～220V range regulation, and the there-necked flask 31 of heating 2000ml produces water vapour.The water vapour that takes place enters into reaction chamber 21 by the corrugated stainless steel tubing that links to each other with reaction chamber.Twine the ribbon heater heating on the corrugated stainless steel tubing, make it temperature and be higher than 100 ℃, avoid water vapour in corrugated tube, to condense.
For the safe operation of assurance device, installed a cover anti-dry control device 28 additional, the water level in there-necked flask 31 is lower than the lowest water level of setting prescribes a time limit, and can guarantee the safe operation of test unit automatically with the power supply disconnection of electric jacket 30.
(4) reaction chamber and control system
It is the bigger middle temperature tube type resistance furnace of thermal capacity of 4kW that heating furnace 23 is selected power for use, size of burner hearth be 60 (φ) * 1000 (L) (mm), be not less than 250mm in the zone of constant temperature that is lower than 800 ℃ temperature pipe type stove.Because this fluctuation range of testing desired test temperature is very little, so select a high Accuracy PID electron temperature-control instrument for use, its measuring accuracy is ± 0.2%F.S ± 1 character that the control accuracy of furnace temperature is ± 2 ℃.
The stop valve 32 of water vapour is connected with the draft tube 22 of reaction chamber, at inlet end one stop valve 19 is arranged, and can control the water vapour amount that enters in the reaction chamber.
The invention has the beneficial effects as follows:
