Methane is burned with 30% excess air in an adiabatic reactor. The reactants enter at 298 K. Determine the temperature of the products. Assume variable specific heats (i.e., use the gas property table and/or the book tables).
Methane gas is burned with 30 percent excess air. This fuel enters a steady-flow combustor at 0.9 atm and 25'C and is mixed with the air. The products of combustion leave this reactor at 0.9 atm and 1600 K. Determine the equilibrium composition of the products of combustion and the amount of heat released by this combustion in kJ/kmol methane. Use data from the tables.

Methane (CH4) is burned with 110.9 % of theoretical air. The mixture enters the combustion chamber at 25°C. 1) Find the Air/Fuel ratio for this mixture: AF = (+ 0.03) 2) Find the adiabatic flame temperature for the mixture. Tadiabitic flame = OC (+ 20°C) 3) Find the mole fraction of the N2 in the exhaust. YN2 =
For calculating an "adiabatic flame temperature" it is customary to assume that the reactants (input) are at the reference temperature (298 K or 537 oR). Psi is equal to 3 Your assigned value of wis (You will lose 1 pt if this is blank). Methane (CH) is burned with (110 +0.3 )% of theoretical air. (Hence, if y = 3 the methane is burned with 110.9% theoretical air). The mixture enters the combustion chamber at 25°C. A) Find the Air/Fuel...
100 moles/h of methane is burned with 100% excess air. The percent conversion of methane is 70%. Of the methane burned, 32% is reacted in partial combustion and the balance reacts in complete combustion. The reaction schemes are shown below: (1) CH4 + 2O2→ CO2 + 2H2O (2) CH4 + 3/2O2→ CO + 2H2O a. Draw a flow chart for this process b. Calculate the inlet air flow rate in moles/h c. Calculate the molar flow rate in moles/h and...
fuel mixture containing methane and butane is burned with excess air in a fumace and the flue gas consists of 90 mOles of carbon dioxide, 10 moles of carbon monoxide, 150 moles of water and 15 moles of oxygen. Determine the ratio of the two fuels and excess air percent. 30 points
4.1 Calculate the length of the turbulent diffusion flame formed when pure methane is released at high pressure through a nozzle 0.1 m in diameter. Assume that the flame temperature for methane is 1875°C (Lewis and von Elbe, 1987) and the ambient temperature is 20°C. What would the length be if the nozzle fluid consisted of 50% methane in air?
In your grades section of Blackboard, you will find a column: "data Q5"". These columns contain the value y. Your assigned value of y is _5_ (You will lose 1 pt if this is blank). Methane (CH4) is burned with (110 +0.3 y)% of theoretical air. (Hence, if y = 10 the methane is burned with 113% theoretical air). The mixture enters the combustion chamber at 25°C. 1) Find the Air/Fuel ratio for this mixture: AF = (+0.03) 2) Find...
