Problem 1: Methane gas is burned with 10% excess air at a pressure of 1atm in a furnace. The methane burns completely to form CO2 and water with 100% conversion. The methane enters the furnace at 25.0C and while the air is preheated and enters at 200C. Everything leaves the reactor together at 500C and 1 atm. a) Determine the amount of heat generated (in kW ) for a basis of 100mol/sH4 that enters the furnace. Indicate whether this value is positive or negative and if heat enters or leaves the system. b) Review (Ch6): The combustion products leaving the furnace include water vapor, unburned oxygen gas, CO2 and nitrogen gas. Determine the dewpoint of combustion products leaving the furnace assuming that water is the only condensable species c) Review (Ch7): The heat produced from the combustion is used to generate superheated steam. How much 500C,40 bar steam can be made if water is supplied at 40 bar and 50C
