Case Study #2 – Food Processing
Subject: HJ Heinz Processing Plant
Product: Circular Econopak
| Application |
- circular Econopak designed and manufactured for natural gas-fired 400 hp fire-tube steam boiler
|
| Analysis |
- stack gas temperature lowered from 480° F to 315° F at full-fire conditions
- water temp in Economizer increased from 227°F to 275°F
- 165°F differential translates to fuel savings of 674,123 Btu/hr at full fire
- 4% increase in boiler efficiency
