| Comparison on Energy Conservation between Thermal Oil Heating and Far-infrared Heating in Reaction Kettle |
| Take the example of 3,800 L water kettle: |
| C/N |
Heating Method |
Thermal Oil and Electric Bar Heating |
Far-infrared Heating |
Notes |
| Sorts |
| 1 |
Designed Power |
168KW |
120KW |
|
| 2 |
Power Distribution |
Heated by 8 electric bars |
High, meddle and low-part heating |
|
| 3 |
Response to Heat |
Needs 1.5 hours and 250 Kwh to heat 1 ton of thermal oil in jacket to 280 ℃ |
After having been electrified for 30 minutes, the outer wall of reaction kettle reaches at 400 ℃ and needs 42 Kwh |
|
| 4 |
Actual Power |
Full-loaded operation in 160 KW |
Only need middle and low parts, totally 84KW, to satisfy the technical requirement |
|
| 5 |
Electric Consumption by One Kettle of Material |
Needs 1764 kwh for reacting one kettle of material |
Needs 814 kwh for reacting one kettle of material |
Save 53% |
| 6 |
Required Security Standard |
Electric-heating bar is not blast proof |
Overall structure of heater meets with anti-blast standard and gains the related certificates |
|
| 7 |
Environmental Influence |
Since thermal oil needs to add propylbiphenyl mixture, the leakage of oil gas under the high temperature will be harmful to human body. |
No pollution, noise , carbonization or coking of material in operation |
|
| 8 |
Suitable Reaction Temperature |
Suitable range within 300 ℃ |
Suitable range within 700 ℃ and to be set randomly |
|
| 9 |
Normal Loss |
Change the oil or bar at lease once a year for thermal oil is easy to be carbonized. |
Without any expenditure in 3 years and easy installation and check |
Save cost of 10,000 Yuan/year |
| 10 |
Heat Conduct Theory |
After heating jacket, the oil will transfer the heat into kettle to let material be heated. |
Electric resistance sends the heat after being electrified, then carborundum evenly radiates heat onto materials in kettle through infrared rays. |
|
| Results: after comparing two different heating methods, far-infrared radiation heating can save 53% more energy than thermal oil heating. Manufacturing one kettle of material can save 950 kwh to annually reduce the cost of 1 ton of thermal oil and loss for changing electric-heating bar and maintenance. Since far-infrared heating is rapid and stable, user’s output and product quality can get improved. Furthermore, staff labor intensity and working condition can also be better. What’s more, far-infrared heater has the advantages of reasonable structure design, beautiful appearance, easy installation and operation, easy temperature control (for high, medium and low parts) as well as safety and explosion prevention. |
