If fluid flow control is 2L/min, the circulation process of liquid stabilising is realized；
6th step starts the heating power supply in described device, according to preset heating temperature, such as fire box temperature control
800 DEG C are made as, heater strip is controlled by hearth thermocouple and reaches predetermined temperature；
7th step records fluid flow and fire box temperature after fire box temperature is stablized；It is surveyed by feed liquor thermocouple
Feed liquor temperature is measured, measured value is 22 DEG C；Go out liquid temperature by going out liquid thermocouple measurement, measured value is 72 DEG C；Pass through bottom plate thermoelectricity
Even measurement sole plate metal temperature, measured value are 328 DEG C；
8th step opens the tapping valve in described device, heating system remaining liq is discharged into liquid storage after the test
In tank, heating system is cleaned out.
Room temperature when due to test of many times can make the test(ing) liquid temperature in fluid reservoir occur there may be difference
Small change subtracts feed liquor temperature with the liquid temperature out of heated liquid and obtains to eliminate the test error that room temperature variation generates
The heating temperature difference represent Important Parameters of the effective heat duty of practical heating furnace, the corresponding operating condition (one) without dirty layer, on
Stating the heating temperature difference that specific implementation case method obtains is 276 DEG C.
Corresponding operating condition (two) have dirty layer situation, and specific implementation case method is made of following steps:
The first step, it is preparing described device with the above-mentioned cylinder bottom plate without dirty layer method same material, install entire dress
It sets；
Second step prepares certain thickness dirt layer on cylinder bottom plate in said device；
The method of specific prefabricated dirty layer are as follows: be crushed the dirty layer for being derived from live heating furnace fire tube, with a small amount of water and micro original
After oil dilution, be laid on the cylinder bottom plate according to certain thickness, slowly sedimentation and heating air-dry, measure dirty layer with a thickness of
24mm；
Third step prepares with above-mentioned without the identical test(ing) liquid of dirty layer method, such as+80% water of 20% crude oil of volume proportion,
It is added in the fluid reservoir of described device；
4th step starts the blender in the fluid reservoir, and grease liquid is stirred evenly；
5th step starts the liquid feeding pump in described device, opens liquid feed valve and liquid valve, makes test(ing) liquid by heated system
Cooling tank is flowed into after system；
6th step observes the flow meter data in described device, sets identical liquid without dirty layer method according to above-mentioned
Flow, such as fluid flow control are 2L/min, adjust liquid feed valve, are allowed to that fluid flow is identical, realize the circulation of liquid stabilising
Process；
7th step starts the heating power supply in described device, goes out liquid and feed liquor without the measurement of dirty layer method according to above-mentioned
276 DEG C of the temperature difference, due to there is metal heat transfer efficiency decline when dirty layer, burner hearth is turned up and controls temperature, when fire box temperature is increased to 970
DEG C, reach identical liquid out and 276 DEG C of the feed liquor temperature difference；
8th step, after fire box temperature is stablized, with the above-mentioned fluid flow 2L/min without dirty layer method and out liquid with
In 276 DEG C of identical situations of the feed liquor temperature difference, 970 DEG C of fire box temperature are recorded, passes through bottom plate thermocouple measurement sole plate metal temperature
Degree is 368 DEG C；
9th step opens the tapping valve in described device, heating system remaining liq is discharged into liquid storage after the test
In tank, cylinder bottom plate is disassembled, dirty layer is removed, cleans out heating system；
Tenth step, preset multiple thickness dirt layers, such as: 15mm, 31mm, 40mm, 46mm are carried out multiple using the method
Test and detection, obtain sole plate metal temperature corresponding to different-thickness dirt layer, referring to following table:
| Dirty thickness degree | 0mm | 24mm | 31mm | 40mm | 46mm | 50mm |
| Sole plate metal temperature | 328℃ | 368℃ | 395℃ | 436℃ | 457℃ | 481℃ |
As can be seen from the above table, in operating condition (one) and operating condition (two) identical fluid flow and liquid and the feed liquor temperature difference out
In the case of, there is the sole plate metal temperature of dirty layer to be higher than the sole plate metal temperature without dirty layer, and as dirty layer thickeies, sole plate metal
Temperature increases bigger.
What the sole plate metal of the method was selected is the common Q245R material of crude oil heater fire tube, is recommended to use temperature
Spending the upper limit is 430 DEG C, is more than that this temperature long term high temperature uses, Q245R can occur pearlitic spheroidization, graphitization, high-temerature creep and add
Phenomena such as acute, intensity sharply declines generates security risk.
As can be seen from the above table, when dirty thickness degree reaches 40mm, the temperature of the Q245R material as sole plate metal is higher than
It is recommended to use 430 DEG C of temperature upper limit, and dirty layer is thicker, and metal overtemperature degree is bigger, therefore, in the certain operating condition (grease of heating furnace
Ratio, fluid flow and liquid and the feed liquor temperature difference out) in the case of, determine that the dirty thickness degree of its deposition is not greater than 40mm, thus
Technological guidance is provided for furnace design selection and descaling cycle.
