Steam is produced in a boiler using methane as a fuel. 1000 mol/h of methane at 25°C is burned in the boiler with 10% excess air at 100°C. The fractional conversion of methane is 0.9 and the ratio of CO₂ to CO in the combustion products is 10.0. The combustion product leaves the boiler at 400°C. Heat released by the combustion is accepted by steam. The greater the value of heat released, the more steam is produced in the boiler. a. Calculate the amount (mol/h) of air required. (10472 mol/h) b. Calculate the amount of heat transferred in the boiler (kW). (-162.4 kW) c. Does the steam production decrease or increase if you i. Increase the temperature of the inlet air ii. Increase the combustion product temperature.

Question
Transcribed Image Text:Steam is produced in a boiler using methane as a fuel. 1000 mol/h of methane at
25°C is burned in the boiler with 10% excess air at 100°C. The fractional conversion
of methane is 0.9 and the ratio of CO₂ to CO in the combustion products is 10.0.
The combustion product leaves the boiler at 400°C. Heat released by the combustion
is accepted by steam. The greater the value of heat released, the more steam is
produced in the boiler.
a. Calculate the amount (mol/h) of air required. (10472 mol/h)
b. Calculate the amount f heat transferred in the boiler (kW). (-162.4 kW)
c. Does the steam production decrease or increase if you
i. Increase the temperature of the inlet air
ii. Increase the combustion product temperature.
