Methane at $25$ deg C is burned in a boiler furnace with $10\mathrm{.}0\%$ excess air preheated to $100$ deg C$.$ Ninety percent of the methane fed is consumed, the product gas contains $10\mathrm{.}0$ mol CO$2/$mol CO$,$ and the combustion products leave the furnace at $400$ deg C$.$ Calculate the following from the furnace for a basis of $1000$ mol CH$4$ fed$/$s$.$
