Smoke volatility index

Smoke volatility index. The smoke volatility index shall be computed from the following equation ... 

Kerosene can vary widely in its burning quality as measured by carbon deposition, smoke formation, and flame radiation. This is a function of hydrocarbon composition—paraffins have excellent burning properties, in contrast to those of the aromatics (particularly the polynuclear aromatic hydrocarbons). As a control measure the smoke point test (ASTM D-1322, IP 57) gives the maximum smokeless flame height in millimeters at which the fuel will burn in a wick-fed lamp under prescribed conditions. The combustion performance of wide-cut fuels correlates well with smoke point when a fuel volatility factor is included, because carbon formation tends to increase with boiling point. A minimum smoke volatility index (SVI) value is specified and is defined as ... 

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. 

Smoke Volatility Index is thought to be significant but it has not been completely investigated. The relationship between smoke point and Characterization Factor appears to be much the same (slightly lower smoke points) as that shown for kerosene in Table 4-21, but the variations are larger. Scant information on the weight of carbon deposits in one type of reactor indicates the following ... 

Other important properties include Hash point, volatility, viscosity, specific gravity, cloud point, pour point, and smoke point. Most of these properties are related directly to the boiling range of the kerosene and are not independently variable. The flash point, an index of fire hazard, measures the readiness of a fuel to ignite when exposed to a flame. It is usually mandated by law or government regulation to be 120° or 130° F (48° or 72° C), Volatility, as measured... 

Polysulfones are self-extinguishing resin. Polysulfones with no flame retardant additives has been given 94V-0 under the UL Standards. The value of limited oxygen index (around 0.40) points out their excellent flame retardancy [109]. Furthermore, exposed to flame, polysulfones emit very little smoke or toxic volatiles. However, the high flameproof properties of polysulfones are scanty when they are used as electriccd parts or in an epoxy resins network. Poly(sulfone) (PSF) and p>oly(ether sulfone) (PES) are commonly used for high performance applications such as advanced...
