The desired gas temperature exiting the flame mixing chamber and entering the reaction chamber of a thermal incinerator is 600oC. The polluted airflow rate is 550 m3/min at 77oC. The fuel gas (methane) is available at 20oC and the flare draws in supplemental air (at 25oC) at a rate of 14 air/kg fuel gas. Calculate the required flow of methane. Ignore the heat losses and heat generation from the pollutant combustion (that part of the flare would be too difficult to predict based on the variable emissions). Give your answer in kg/min and in m3/min
