4 Eclipse TFB, V2, Design Guide 310, 11/14/2014Product DescriptionThe TFB is a nozzle-mixing burner designed for tube firingapplications with multiple fuel capability. The burnerconsists of a housing, rear cover, air and fuel inlet blocks,spark rod, flame rod (if selected), UV scanner adapter (ifselected), gas tube, nozzle and air shroud.Burner design provides:• Adjustable air shroud to maintain correct air velocityfor different sized tube applications and fuels.• Uniform tube temperatures for extending tube life.Heat ExchangerThe TFB can be used with or without an exhaust legrecuperator. An exhaust leg recuperator is a heatexchanger that transfers heat from the exhaust air to thecombustion air. Preheating the combustion air canincrease the fuel efficiency by as much as 20%. The TFBcan handle combustion air temperatures up to 1000°F.The recommended recuperators for the TFB are theEclipse Bayonet (Data 317) and the Bayonet-Ultra (Spec.318).Figure 1.1.
