100-800 HP CBEX Elite The air openings are to be 5 feet above floor level. • • • • Air required: 1000 x 10 = 10000 cfm (from 2B above). Air velocity: Up to 7 feet = 250 fpm (from 3 above). Area Required: Area = cfm/fpm = 10000/250 = 40 Sq-ft total. Area/Opening: 40/2 = 20 sq-ft/opening (2 required). Notice Consult local codes, which may supersede these requirements. Stack/Breeching Size Criteria The design of the stack and breeching must provide the required draft at each boiler flue gas outlet. Proper draft is critical to burner performance. Although constant pressure at the flue gas...
