Automotive Case Study
Case Study #4 – Automotive
Subject: Firestone Tube Company, Russellville, Arkansas
Product: Circular Economizer
| Application |
- box economizer designed and manufactured for 22,000 pph steam boiler firing heavy fouling fuel
- unit fabricated with hot-forged return bends, removable end panels and sootblowing provisions of standard carbon steel; designed to rest on support steel with an expansion joint, mounting directly to boiler outlet
- inlet gas temperature from boiler to Economizer 425° F
|
| Analysis |
- stack gas temperature lowered from 620° F to 330° F at full-fire conditions
- water temp in Economizer increased from 250° to 320°
- 290° differential translates to fuel savings of 1,557,439 Btu/hr at full fire
- 7% increase in boiler efficiency
