法国 AD 全自动烟点测定仪 SP10

烟点的测试方法是石油行业中最古老的测试方法之一，也是从未自动化的手动测试方法之一。手动测试要求具有经验、熟练的技术人员，而且测试很耗时间。
如今试验中依靠目测作为评定方法的缺点在于受操作人员主观判断的限制。目测的方法对实验人员来说也是非常具有挑战性和危险性的。
The SP 10 带来了烟点检测的新手段。它使用了摄像机观测火焰并可调节火焰大小的系统。当火焰达到测试方法要求的形状时，The SP 10 会对火焰高度进行存储和报告。

优点
1.快速、简单、实用 
2.提高安全性
3. 降低劳动力 
4.以更高的精度严格模拟手动测试方法 
5.简洁的设计

意义和用途
本方法为处在火焰状态下的煤油和航空涡轮燃料提供了有关发烟性能的指标。烟点与组成这些燃料的碳氢化合物的类型有关。一般情况下，燃料中含有的芳香烃越多，发烟性越大。一个高的烟点表示这种燃料具有较低的发烟趋势。
烟点很大程度上与燃料燃烧中辐射热能的热传递有关。因为辐射热能的传递受到燃烧器金属温度和其他燃气涡轮部分发热区域的强烈影响，而烟点则为这些部件相接触的燃料提供了相关燃料特性的依据。

原理
The SP 10 采用了以能够观测火焰和调整火焰大小驱动器的摄像机为基础的专利系统。火焰的图像是数字化的，而且当火焰的形状符合测试方法中所要求的时候，有专门的软件用于确定火焰的高度。

The smoke point method is one of the oldest test methods in petroleum industry. It is one of the last manual methods that has never been automated before. To be able to run manually this test, it requires high skilled technicians with a long experience and in addition it is time consuming.
    The current visual rating method used for specification purposes suffers from the drawback of operator subjectivity. The visual measurement of an open flame is a very challenging exercise and very dangerous for lab personal.
    The SP 10 revolutionizes this test. It uses a system that adjusts the size of the flame associated to a video camera that observes the flame. When the flame gets the shape described in the test method, the SP 10 memorizes and reports the height of the flame.

Benefits
1、Quick, easy, and objective rating
2、Increases safety
3、Reduces labor
4、Mimics strictly the manual method with improved precision
5、Very compact design

    The SP 10 is an automated instrument that strictly follows the test method with an improved precision. It eliminates the subjectivity inherent to the manual test. The visual rating of the flame varies from one operator to another. Thanks to the digital imaging, the height of the flame which has the shape described in the test method is precisely observed and it is always 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.

Significance and Use
    This test method provides an indication of the relative smoke producing properties of kerosines 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.

Principle
The SP 10 uses a patented system based on a video camera that observes the flame and an actuator thatadjusts 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.
