  2. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    energy/volume of the fuel; There are two kinds of enthalpy of combustion, called high(er) and low(er) heat(ing) value, depending on how much the products are allowed to cool and whether compounds like H 2 O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter. Low heat values are calculated from high ...

  3. Oxy-fuel combustion process - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_combustion_process

    The justification for using oxy-fuel is to produce a CO 2 rich flue gas ready for sequestration. Oxy-fuel combustion has significant advantages over traditional air-fired plants. Among these are: The mass and volume of the flue gas are reduced by approximately 75%. Because the flue gas volume is reduced, less heat is lost in the flue gas.

  4. Oxidizing and reducing flames - Wikipedia

    en.wikipedia.org/wiki/Oxidizing_and_reducing_flames

    It has an opaque yellow or orange color due to carbon or hydrocarbons [3] which bind with (or reduce) the oxygen contained in the materials the flame processes. [2] The flame is also called carburizing flame , since it tends to introduce carbon soot into the molten metal.

  5. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    Propane Iso-Octane (2,2,4-Trimethylpentane) In daily life, the vast majority of flames one encounters are those caused by rapid oxidation of hydrocarbons in materials such as wood, wax, fat, plastics, propane, and gasoline. The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1,950 ...

  6. Cubic equations of state - Wikipedia

    en.wikipedia.org/wiki/Cubic_equations_of_state

    In that situation, the reduced cubic equation of state yields 3 solutions. The largest and the lowest solution are the gas and liquid reduced volume. In this situation, the Maxwell construction is sometimes used to model the pressure as a function of molar volume.

  7. Reduced properties - Wikipedia

    en.wikipedia.org/wiki/Reduced_properties

    In thermodynamics, the reduced properties of a fluid are a set of state variables scaled by the fluid's state properties at its critical point. These dimensionless thermodynamic coordinates, taken together with a substance's compressibility factor , provide the basis for the simplest form of the theorem of corresponding states .

  8. Redlich–Kwong equation of state - Wikipedia

    en.wikipedia.org/wiki/Redlich–Kwong_equation_of...

    p is the gas pressure; R is the gas constant, T is temperature, V m is the molar volume (V/n), a is a constant that corrects for attractive potential of molecules, and; b is a constant that corrects for volume. The constants are different depending on which gas is being analyzed. The constants can be calculated from the critical point data of ...

  9. Compressibility factor - Wikipedia

    en.wikipedia.org/wiki/Compressibility_factor

    In a compressibility chart, reduced pressure is on the x-axis and Z is on the y-axis. When given the reduced pressure and temperature, find the given pressure on the x-axis. From there, move up on the chart until the given reduced temperature is found. Z is found by looking where those two points intersect. the same process can be followed if ...
