A chemical plant produces waste gas that is used as a fuel for heating. The volumetric composition of the fuel is: Methane (CH4) = 75.0 % Ethane (C₂H6) = 19.0 % Carbon dioxide (CO2) = 6.0 % In the boiler, the fuel is burned with an excess air of 22 % and the total heat transfer to the boiler heat exchanger is 284 MJ per kmol of fuel burned. The fuel and dry air enter the burners at 25°C and 1 atm. Determine: a) The stoichiometric reaction scheme for the fuel; b) The actual reaction scheme for the fuel burning in the boiler; c) The dewpoint temperature of the combustion products [K], assuming the products are at a pressure of 110 kPa; d) The combustion product temperature [K]. You may use the following data in your calculations: Substance CH4 C₂H6 0₂ N₂ H₂O(g) CO₂ hfº kJ/kmol -74 850 -84 680 0 0 -241,820 -393,520 hº kJ/kmol 8682 8669 9904 9364 A chemical plant produces waste gas that is used as a fuel for heating.
