A natural gas containing 82 mole% CH, and the balance C2H6 is used as a fuel to generate steam in an industrial plant (Figure 2). The natural gas is fed into a furnace at 25°C and burned at a rate of 10.000 mol/hr with 20% excess air. The heat transferred from the furnace is used to convert a liquid feed water at 25 °C into a saturated steam at 30 bar. During the combustion of natural gas, all the CH,...

A gas mixture at 1500 K with the molar analysis 10% C02, 20% H2O, 70% N2 enters a waste-heat boiler operating at steady state, and exits the boiler at 750 K. A separate stream of saturated liquid water enters at 25 bar and exits as saturated vapor with a negligible pressure drop. Ignoring stray heat transfer and kinetic and potential energy changes, determine the mass flow rate of the exiting saturated vapor, in kg per kmol of gas mixture
