| -Flexible Heating Jacket Test- |
| In order to fully understand KM-EL flexible heating jacket's material's ability to reduce heat loss and power consumption, we set up an experiment on July 2008, to simulate actual pipeline heating .The objective of the test is to compare the power consumption of the materials under the same environment and temperature. |
| Experiment Description: Compare the power consumption of the glass needle blanket 13mm (t) and SIB blanket 10mm (t) |
| Heating Layer: ∮ 4 " x 800mm (L), 220VAC, 620W, 2.8Amp-2 parts, parallel (Figure 5) mounted on the |
| |
Sample 1: Inner : 0.4mmt glass cloth insulation layer: 13mmt glass needle blanket. Outer : 0.4mmt PTFE coated fiberglass fabric (the current market standard)
Sample 2: Inner : 0.4mmt glass cloth insulation layer: 10mmt SIB blanket. Outer : 0.4mmt PTFE coated fiberglass cloth
Measuring instruments - watt-hours (kwh), watches |
| Experiment steps: |
Figure 5 |
| 1. |
Electrically heat the sample to 150°C, (sample 1) |
| 2. |
Start timing (Figure 1) (sample 1) |
| 3. |
Wait for a duration of 4 hours (Figure 2) (sample 1) |
| 4. |
Switch to the second sample, and repeat the above steps (sample 2) |
| 5. |
End the timing after duration of 6 hours (Figure 4) (sample 2) |
| Result: |
| 1. |
Insulation material - glass needle 13mm (t) - after 4 hours with the consumption of 1.5 kWh, has an average of 0.375 degree / hr |
| 2. |
Insulation material - SIB 10mm (t) - after 6 hours with the consumption of 1.6 kWh, has an average of 0.267 degree / hr |
| 3. |
With using a glass needle blanket, 13mm (t), ∮4 "power required per m 0.234 kWh / hr |
| 4. |
If the use of SIB blanket 10mm (t), ∮4 "power required per m 0.167 kWh / hr |
| 5. |
SIB blanket with 10mm (t) will reduce power consumption by 28.8% |
