Nominal boiling range

Table IV gives the properties of the SRC-II fuel oil compared to a low-sulfur residual oil utilized in a recent combustion test. The SRC-II fuel oil is a distillate product with a nominal boiling range of 350-900°F, a viscosity of 40 Saybolt seconds at 100°F and a pour point below -20°F. Thus, it is readily pumpable at all temperatures normally encountered in transportation of the fuel oil. The fuel oil has a very low content of ash and sediment as well as a low Conradson carbon residue. These characteristics are favorable from the standpoint of particulate emissions during combustion. Tests of compatibility with typical petroleum fuel oils and on stability of the coal distillates over time have not revealed any unusual characteristics that would preclude utilization of these coal-derived fuels in conventional boiler applications.

In this program, two types of fuel oil blends were combusted. One type of blend was derived only from primary liquefaction products, VGO and solvent, having a nominal boiling range of 350 to 1000°F and are referred to as 350-1000°F blends. Fuel oils were also blended by adding coker liquids, containing 1000°F+ material, to the 350-1000°F blends and are referred to as 350°F+ blends.

Nominal boiling range Nominal boiling range is the difference in the atmospheric boiling points of the lightest and heaviest components in the system. 

For multicomponent systems with nominal boiling range less than 83 C, the design o) parameter should be the controlling (o, calculated using Equation 4.50 to Equation 4.52. 

For a multicomponent system with nominal boiling range more than 83°C, the 0) parameter is to be estimated using Equation 4.52. 

The calculation depends on the range of nominal boiling point. If the range is less than 83°C, the omega parameter (co) is estimated by using the controlling of Equation 4.50, Equation 4.51, or Equation 4.52. If the nominal... 

This table gives the thermal conductivity of about 275 liquids at temperatures between -25 and 100 °C. Values refer to nominal atmospheric pressure when an entry is given for a temperature above the normal boiling point of the liquid, the pressure is understood to be the saturation vapor pressure at that temperature. Reference 1 contains data on many of these liquids at high pressures. Data on halocarbon refrigerants over a wide range of temperature and pressure may be found in Reference 6.
