Reduce Fuel, Reduce Costs, and Get Fast Payback.

Reduce fuel and fuel costs. Economizers are fabricated assemblies offinned tubing that recycle heat produced by your boiler. They remove heatfrom the flue gases and return it to the boiler feedwater. So less fuel isrequired by the boiler to generate a given amount of steam.

Versatility. Install in- or outdoors; orientations may be vertical or horizontal; and versatility equals lower installation costs.

Decrease thermal pollution. By removing heat from the boiler’s fluegases, an economizer lowers the temperature of these gases before theyexit into the atmosphere.

Guaranteed thermal performance. All Superior packaged economizers are backed by a performance guarantee. Each individual unitis computer designed to match exactly the operating characteristics of theboiler on which it will be used.

Expect only the best from Superior Economizers.

• Performance of every Superior unit is guaranteed.

• Equipment is guaranteed for 12 months from date of instal-lation or 18 months from shipment, whichever is earlier.

• Superior Boiler has teamed-up with Kentube to design and-manufacture the pressure tubing, produce the finning, andfabricate the economizers, thus insuring quality controlover the major constituents that make up the heatexchangers.

HOW IT WORKS

YOUR APPLICATION: CHOOSE:

FFiinnnneedd ttuubbiinngg

• Superior’s traditional economizer line

• Normally used for larger industrial watertube boilers

• Very adaptable to a wide variety of applications rang-ing in size from 15,000 PPH to 500,000 PPH andgreater

• The most flexible design with configurations for:

- Vertical or horizontal gas flow- Finned or bare tube designs- Clean or dirty fuels- Many other options- Modular designs available

If your boiler application is larger (from 13,800 PPH to100,000 PPH), the Superior specially designed andmanufactured cylindrical economizer is for you.

• Incorporate a traditional design with water flowingon the inside of the tubes and with gas circulatingover high frequency, resistance-welded fins

• Designed to fit into the stack

• Includes a sootblower integral to the unit

• Due to the circular design, doesn’t require costly transitions

• Less expensive, and installation costs are also typically lower

• Designed and fabricated underthe stringent requirements ofASME Section I or VIII, so youcan absolutely depend on theunit’s integrity

This revolutionary little economizer has madeits mark on the industry with big savings.

No costly transitions andlower installation costs.

Big applications, big flexibility.

• Lightweight, adaptable and designed specifically for smaller firetubeboiler applications

• Ranges in size from 40 HP to 500 HP

• Built to ASME Section I

• Heat recovery system to save fuel andmoney

• Small initial cost

• Results in big fuel savings

• Payback times are amazingly short

• The flue gases stay inside tubes; efficiently handles your boiler’sload changes

• Does away with the need for expensive flue gas bypasses

• Cylindrical design easily adapts to the boiler opening or stack, thuseliminating expensive transitions

• Water is on the outside of the tubes; works with on/off andproportioning feedwater systems

• Vertical or horizontal installation
