You have 3 moles of hydrocarbons on the LHS (1+1+1); 1 mole of this mixture produces 2 moles of CO2 But why do you write that equation? You are told the composition of natural gas, and it is not 1:1:1. Try using the correct proportions. (As a rough estimate, since it is 90...
The derived equation shows the AFT at different natural gas compositions along with different process parameters such as the amount of excess air. Thus, the required combustion temperature can be controlled by adjusting the natural gas composition or the combustion temperature can be specified based ...

Here we collated observation data of natural N isotopes (expressed asδ15N,δ15N = (15N/14N)sample/(15N/14N)standard−1, where atmospheric N2is used as the standard) of primary v-NH3and c-NH3emission sources (Supplementary Fig.2), NH3gas in the ambient atmosphere (a-NH3), NH4+...
Wilhelm Scheeleas an active fraction of air that sustained combustion. Lavoisier called the gas “oxygen.” Lavoisier’s theory that combustion was a reaction between the burning substance and the gas oxygen, present only to a limited extent in theatmosphere, was based on scientific principles, ...
Natural Gas Conversion V Ola Olsvik, Roger Hansen, in Studies in Surface Science and Catalysis, 1998 2.2 Combustion Four different turbulent combustion model were implemented and tested: (1) Mixed Is Burned (MIB), 2) Eddy Dissipation Concept (EDC), 3) Eddy Break Up (EBU), 4) Double Delta...
Theheat of combustion(energy content) of natural gas is the amount of energy that is obtained from the burning of a volume of natural gas, measured in British thermal units (Btu). The value of natural gas is calculated by its Btu content. One Btu is the quantity of heat required to rai...
Fig. 3.67 shows the variations of CO2 and O2 with air ratio for different fuels of natural gas, heavy oil of bunker C and bituminous coal. Volume fraction of CO2 in combustion gas in dry basis differ between fuels. However, variation of fuel has little effect on the dependence of air rat...
Uncertainty analysis results indicated that γ (parameters in the quadratic interpolation equation), compression ratio, mass and lower heating value of natural gas trapped in the cylinder, overall trapped mass, and ignition delay were important contributors to the overall uncertainty in predicted cylinder...
