Smoke point aviation fuel

The low-density products manufactured in the SMDS process are predominantly paraffinic and free from impurities such as nitrogen and sulphur. Both the kerosine and gas oil have excellent combustion properties (smoke point and cetane number), and their cold-flow characteristics meet all relevant specifications - even the stringent freezing point requirements of aviation turbine kerosine. They also make excellent blending components for upgrading low-quality stock that would otherwise have to be used in fuel oil. The excellent quality of the products was proved in extensive engine tests.

Smoke Point of Kerosine and Aviation Turbine Fuel ... 

This test method covers a procedure for determinatioii of the smoke point of kerosine and aviation turbine fuel. ... 

This test method provides an indication of the relative smoke produdng 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 produdng tendency. 

Bias—The procedure in Test Method D 1322 for measuring the smoke point of kerosines and aviation turbine fuels has no bias because the value of the smoke point can only be defined in terms of a test method. 

The combustion quality of aviation turbine fuel has traditionally been controlled in specifications by such tests as smoke point, smoke volatility index, aromatic content of luminometei number. Evidence is accumulating that a better control of the quality may be obtained by limiting the minimum hydrogen content of the fuel.
