The Minimum Ignition Temperature Test Instrument is a way of testing the sensitivity of the ignition that the dust cloud is in the heated environment.
Usage of the tester:
When a lot of dust is exposed in heating the air and the air temperature is high enough, it may lead to spontaneous combustion. This method can test the minimum ignition temperature of combustible dust cloud.
| No. | Item Name | |
| 1 | Furnace operating temperature range | Room temperature ~ 800 ºC. The operating temperature can rise to 1000 ºC to clean the test chamber |
| 2 | Temperature accuracy | ± 1% (higher than 500 ºC), ± 3% (lower than 300 ºC) |
| 3 | Pressure of the dispersion air chamber | 0 - 1 bar |
| 4 | Pressure accuracy of the air storage device | 5% |
| 5 | Dimension | 500*300*450 mm |
| 6 | Power supply | 230v / 50Hz or 110v / 60Hz |
IEC 61241-2-1:1994:
Electrical apparatus for use in the presence of combustible dust - Part 2: Test methods - Section 1: Methods for determining the minimum ignition temperatures of dust;
The Test is carried on the in Godbert-Greenwald furnace.
The heating furnace is consist of the vertical quartz tubes .
The hole is at the bottom of the tube.
The glass observing room is connected with sample fixing device at the top of the quartz tubes.
The compressed air from the tank blows the dust into the heating furnace and the sample fixing device ,and then exposed into the glass observing room and the quartz tubes.
The heating furnace is located on the holder.
And you can observe the ignition appearance from the bottom of the furnace.
