Methane at 25 degrees Celcius is burned with 46% excess dry air preheated to 100 degrees Celcius. The mixture enters a boiler furnace and generates heat for the production of steam. 90% of the Methane fed is consumed, the product gas contains 10 mol CO2/CO, and the combustion products leave the furnace at 550 degrees Celcius.

What is the rate at which heat is removed from the furnace for a Methane feed rate of 100 mol/second?
