Critical burner dimensions

Critical Burner Dimensions - The position of the flameholder s and burner lines relative to the bottom or the stack is critical for efficient operation. For example, the multijet flare has a turndown ratio of 10 1 when the flameholder centerline is 125 mm below the bottom of the stack but only 2 1 when it is 150 mm above the bottom of the stack. 

Because of the wide variations in operating conditions, tread and carcass blacks cannot be made in the same reactor however, all tread grades can be produced in the same reactor as is the case with all carcass grades. Unfortunately, exact reactor construction details and operating details are proprietary information and cannot be revealed however, exact internal configuration, dimensions, oil spray pattern, and burner design are all extremely critical for optimum quality and yields. One reactor will produce from 20,000-40,000 lbs/day, and a unit consists of from 4 to 5 reactors, discharging into common downstream facilities.
