Conceptual Design for a Coal Mine Gob Well Flare

Flare Tip Diameter. The concept design recommends a minimum flare tip diameter of 24 mm (approximately 8 inches) based on the expected gas flow range and the requirements of 40 CFR 60.18. Flare Height. Based on a 4.7 kW/m2 (1500 Btu/hr-ft2) criteria at the base of the stack, the concept design specifies a 6.1 m (20 ft) overall stack height.
