Question:

An oven heated by natural gas burners has the combustion take place inside a U-shaped steel pipe, so the heating is done from the outside surface of the pipe by radiation. Each burner delivers 15 kW of radiation, burning 110% theoretical air with methane. The products leave the pipe at 800 K. Find the flow(kg/s) of methane. The burner is now switched to oxygen-enriched air (30% O2 and 70% N2), so assume the same conditions as before with the same exit T. Find the new flow (kg/s) of methane needed.
