7 Typical Competition Blower Anatomy 7

8 Centrifugal Impeller vs. Mixed-flow Impeller Advanced mixed flow wheel design combines axial and centrifugal technologies. Air passes through mixed flow wheel at 45 DEG angle. Turbulence is lower for 45 DEG wheel compared to 90 DEG (radial) wheel. Low turbulence means higher efficiency over radial wheel. Flow capability of mixed flow wheel is 2-3 higher than a radial wheel with same diameter 8

9 Rotating Assembly One Piece Chrome-Moly alloy steel pinion Shaft Impeller material available Stainless Steel 120% overspeed tested as standard Balancing Procedure: Pinion Separately Impeller Separately Trim balance of complete assembly. 9

10 Fixed Diffuser Vanes Machined vaned diffuser - not pin-on vanes. High efficiency realized with fully developed flow through impeller and diffuser. 10

11 Inlet Guide Vane Damper High corrosion resistance is standard with stainless steel vanes. Minimum of moving parts - assures high reliability. Mounted vane angle position indicator. Mounted integral to the compressor. 11

12 Typical Competitive Equipment Variable Diffuser Vanes Very complex construction Many, Many more moving parts Variable Inlet Guide Vane 12

13 Air and Oil Seal Unique wind-back labyrinth seal design. Air seal completely separate from gear case to ensure 100% oil free air. Oil seal incorporates an oil slinger ring, a labyrinth seal on the outboard casing side. This prevents oil migration along shaft out of gear case. 13

14 Pinion Shaft Bearings Horizontally split for quick and easy assembly / disassembly. Tilting pad design for excellent stability at high speeds. Field replaceable tilting pads for easy maintenance. Embedded RTD s in pads are available as an option. 14

15 Gears / Thrust Collars Integral thrust collars transfer aerodynamic and gear thrust loads to the bullgear to improve reliability and reduce parasitic horsepower losses Bullgear and bullgear shaft are integral forging. Bullgear made of carbon steel (AISI 1045). 15

16 Input Shaft Seals Input shaft oil seal consists of oil slinger ring and reverse thread labyrinth on shaft with labyrinth seal on gearcase. Oil seal is horizontally split. Driver side bullgear bearing is horizontally split radial journal bearing with integral fixed tilted pad thrust bearings. 16

17 Shaft-Driven Oil Pump Gear-rotor type pump. Mounted on and driven by Input shaft for reliable operation and ensures lubrication to bearings in vent of power failure. Oversized to ensure adequate lubrication to all components. 17

18 Applications Centac CX Series Blowers

19 Waste Water Treatment Blower Applications Industry Requirements: 500 to 30,000 SCFM 5 to 18 psig Customer Value Drivers: Ease of Installation Efficiency Decision Maker: End User / Contractor Where to find them? Food & Beverage Pulp & Paper Refinery Municipalities 19

20 Blower Applications Refinery Refinery Application Combustion Air for SRU Wastewater Treatment for run-off water Misc. gas boosters Most CX Blower opportunities are going to be Combustion Air and WWT Aeration. 20

21 Process Combustion Air for Production Air is supplied to oil burners to produce controlled smoke. Customers Cabot Corporation Continental Carbon Columbian Chemical Misc. others. Blower Applications Carbon Black Production 21

22 Blower Applications Power Plant Flue Gas Desulfurization 22

23 FGD System Schematic Wet FGD System Sulfur in the flue gas is captured by the limestone spray Droplets collect in the slurry at the bottom of the absorber and react with the oxygen in the water to form Calcium Sulfate (Gypsum) Blowers are used to provide air (oxygen) for the appropriate reaction to occur. 23

24 Installations

25 CX 45 Combustion Air Blower The blower shown is installed in a Refinery in Longview, Washington USA. The blower in this application supplies combustion air to a Sulfur Recovery Unit (SRU). This is a very common application used in almost every refinery. Capacity : 15, psig (1750HP) Location : Longview,Washington 25

26 CX35 Combustion Air Blower The blower shown is installed at Cabot Corporation in Franklin, Louisiana. Again, this blower is supplying combustion air, but this time to a Carbon Black manufacturing process. In this process oil is burned under very controlled conditions and the burn carbon that is produced is used for various inks and toners. Capacity : 9, psig (700HP) Location : Franklin, Louisiana 26

27 CX35 Aeration Blower This installation photo illustrates the proper installation of a CX Blower. Note the isolation joints at the inlet and outlet of the machine. These are used to isolate the machine from thermal expansion of the piping system and the blower housing. Capacity : 9, psig (600HP) Location : Philadelphia, Pennsylvania 27
