Question- Size an after burned and specify the flow rate of methane needed to control 800 cfm of air from a paint-drying oven. The oven exhaust gases are available at 250 F. Assume that the design temperature and residence time have been established as 1300 F and 0.6 sec, respectively. The type of burner used in the process requires outside air at a mass ratio of 12:1 (air to fuel gas).Explain the process and each step.
