4. Size an afterburner and specify the flow rate of methane needed to control 8000 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 at 1300 °F and 0.6 sec respectively. The type of burner used in this process requires outside air at a m ass ratio of 12:1 (air to fuel). Ignore VOC combustion and heat losses. 4.
