    There is a 1:1 molar ratio of NH 3 to NO 2 in the above balanced combustion reaction, so 5.871 mol of NO 2 will be formed. We will employ the ideal gas law to solve for the volume at 0 °C (273.15 K) and 1 atmosphere using the gas law constant of R = 0.08206 L·atm·K −1 ·mol −1:

  3. Combustion models for CFD - Wikipedia

    en.wikipedia.org/wiki/Combustion_models_for_CFD

    The k/Ɛ turbulent time scale is used to calculate the reaction rate. A comparison between the turbulent dissipation rates of the fuel, oxidant and products is done and the minimum amongst all is taken as the rate of the reaction. The transport equations for the mass fractions of the constituents are solved using this rate of reaction. [1]

  4. Theoretical oxygen demand - Wikipedia

    en.wikipedia.org/wiki/Theoretical_oxygen_demand

    In the second and third steps, the ammonia is oxidized sequentially to nitrite and nitrate. The ThOD is the sum of the oxygen required for all three steps. We can calculate by following steps: Write balanced reaction for the carbonaceous oxygen demand. CH 2 (NH 2)COOH + 1.5O 2 → NH 3 + 2CO 2 + H 2 O; Write balanced reactions for the ...

    CHEMKIN is a proprietary software tool for solving complex chemical kinetics problems. It is used worldwide in the combustion, [1] chemical processing, [2] microelectronics [citation needed] and automotive [citation needed] industries, and also in atmospheric science. [3]

  6. Thermochemical equation - Wikipedia

    en.wikipedia.org/wiki/Thermochemical_equation

    In thermochemistry, a thermochemical equation is a balanced chemical equation that represents the energy changes from a system to its surroundings.One such equation involves the enthalpy change, which is denoted with In variable form, a thermochemical equation would appear similar to the following:

  7. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

  8. Combustion analysis - Wikipedia

    en.wikipedia.org/wiki/Combustion_analysis

    A combustion train is an analytical tool for the determination of elemental composition of a chemical compound. With knowledge of elemental composition a chemical formula can be derived. The combustion train allows the determination of carbon and hydrogen in a succession of steps:

  9. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    If we make the assumption that combustion goes to completion (i.e. forming only CO 2 and H 2 O), we can calculate the adiabatic flame temperature by hand either at stoichiometric conditions or lean of stoichiometry (excess air). This is because there are enough variables and molar equations to balance the left and right hand sides,
