Presentation on theme: "SER v.3 Sales Presentation Single Ended Recuperative Burner (SER)"— Presentation transcript:
SER v.3 Sales Presentation Single Ended Recuperative Burner (SER)
SER v.3 Sales Presentation Product Features Tube Fired Burner Higher Efficiency than TFB –Burner and recuperator in one product Internal Flue Gas Recirculation –Lower NO x Emissions
SER v.3 Sales Presentation Product History Mature product SER v.1,2 vs. SER v.3 –Single inner tube vs. velocity combustor and ceramic inner tube sections –v.3 includes air and gas orifices, TJ nozzle and Flame-rod option
High Temperature Ranges Metallic – 1000 o C (1850 o F) Hybrid Alloys – 1150 o C (2100 o F) Silicon Carbides – 1300 o C (2400 o F)
SER v.3 Sales Presentation High Temperature Metallic Strengths Cost ( 2 / 3 the cost of most Ceramics) Workability for Fabrication Durability in Handling Repairable in Most Cases Established and Available
SER v.3 Sales Presentation High Temperature Metallic Weaknesses Temperature Limited Reactive to Some Corrosive Environments Gradually Diminishing Strength
SER v.3 Sales Presentation Ceramics Strengths 20% Gain in Temperature Rating Not Reactive to Most Corrosive Environments Limited Diminished Strength over Time Costs gradually Dropping Into Practical Ranges New Manufacturing Techniques Boost Availability and Shape Design
SER v.3 Sales Presentation Ceramic Weaknesses Cost Premium Fragility Special Sealing Considerations Generally Not Repairable Lead Time
SER v.3 Sales Presentation Metallic Tubes Process Temp. o C ( o F) *Dissipation (Flux) Rate kW/m 2 (BTU/hr/in 2 ) 850 (1560)32 (77) 900 (1650)31 (68) 950 (1750)27 (60) 1000 (1830)23 (50) 1050 (1920)18 (40) *Dissipation rate is based on theoretical calculation considering no special environment.
