Smoke Point of Kerosine and Aviation Turbine FuelMã SP: SP10 - Automated Smoke Point ASTM D1322
ASTM and IPreferee method
Quick, easy, and precise
Very compact design
Significance and Use
This test method provides an indication of the relative smoke producing properties of kerosene and aviation turbine fuels in a diffusion flame. The smoke point is related to the hydrocarbon type composition of such fuels. Generally the more aromatic the fuel the smokier the flame. A high smoke point indicates a fuel of low smoke producing tendency.
The smoke point is quantitatively related to the potential radiant heat transfer from the combustion products of the fuel. Because radiant heat transfer
exerts a strong influence on the metal temperature of combustor liners and other hot section parts of gas turbines, the smoke point provides a basis for correlation of fuel characteristics with the life of these components.
The SP 10 uses a patented system (License TOTAL RM) based on a video camera that observes the flame and an actuator that adjusts the size of the flame. The flame image is digitalized and the dedicated software determines the height of the flame when its shape corresponds to the one described in the test method. This specific flame is the one with the maximum height without smoke generation.
The smoke point test with the SP 10 is as simple as is a flash point test with an automated instrument. The operator prepares the candle according to the test method instructions (phase 1).
The candle is then positioned on a conveyor (phase 2).
The operator keys in all sample details and then initiate the test (phase 3).
Then all the procedure is automated. The candle is automatically lit, the five minutes stabilization time is followed by the three determinations of the flame height. At the end of test, the SP 10 instrument calculates the mean value of the three flame heights measured and reports the result.
The result is saved in a built‐in data base. It can be printed, transferred on a USB memory stick and/or send to a LIMS when the SP 10 is connected to a LAN
The SP 10 is an automated instrument that strictly followsthe test method with an improved precision. It eliminates the subjectivity inherent to the manual test where the visual rating of the flame varies from one operator to another. Thanks to the digital imaging technology of SP10, the shape of the flame described in the test method is automatically repeatedly determined andcorresponding flame height is precisely recorded in
the same conditions.
In addition, the SP 10 eliminates all safety risks linked to the visual observation of an open flame. The test is carried unattended which drastically reduces labor. Every test is fully documented and traceable which is important for aviation industry quality procedures.
