Acetylene gas (C2H2) with 20% excess air, fully in continuous regime
incinerated. Air and fuel, separate to the combustion chamber, separate temperature of 250C and 1 atm
under pressure and under reaction, 300,000 to the environment at 250C
kJ / kmol C2H2 is experiencing heat transfer. Combustion end products, combustion chamber 1 atm
leaves the pressure.
a) The end of combustion here means the temperature,
b) Total entropy change for 1 kmol of C2H2,
c) this reaction exergy destruction (usability loss)
You calculate.

Solutions

Expert Solution

Acetylene gas is burned steadily with 20 percent excess air. The temperature of the products, the total entropy change, and the exergy destruction are to be determined.

Assumptions :

  1. Combustion is complete.
  2. Steady operating conditions exist.
  3. Air and the combustion gases are ideal gases.
  4. Changes in kinetic and potential energies are negligible.
