TRANSCRIPT
Eclipse Tube FiringBurnerModel TFB075
Datasheet 310-211/14/2014
All inputs based on gross calorific values.
Eclipse reserves the right to change the construction and/or configuration of our products at any time without being obliged to adjust earlier supplies accordingly.
Plumbing of air and gas will affect accuracy of orifice readings. All information is based on generally acceptable air and gas piping practices.
1 The low firing rate represents the capability of the burner. Achievement of this rate will be affected by the control method and ratio-regulator used in the system design.
2 Total static air pressure required will be the sum of the differential pressures and the static air pressure, as indicated on pages 3 and 4.
3 Gas pressures shown are for system sizing only. Provisions must be made to supply fuel pressure at the burner fuel input port at least 3" w.c. higher than the differential pressure shown in the tables.
4 Flame rod not available with preheated combustion air (PCA). Contact Eclipse if PCA and propane/butane will be used in combination.
5 All weights are approximate.

CO emissions are less than 10ppm (corrected to 3% O2)for furnace temperatures between 1400°F and 1800°FEmissions from the burner are influenced by: • fuel type • combustion air temperature • chamber conditions • percent of excess airFor estimates of other emissions, contact Eclipse Inc.
