A proven method of immediate efficiency gains is reducing flue gas temperature.  Flue gas temperature is the temperature of combustion gases that exit a boiler’s stack.

EconoStak economizers are used to capture and transfer the heat of the flue gas to preheat feedwater back into the boiler.  In most instances, a decrease of the flue gas temperature by 40°F, increases efficiency by one percentage point, resulting in significant cost-savings.

• Decreased operating cost
• Higher boiler operating efficiency
• Reduced fuel consumption
• Reduced emissions/pollutants
• Lower stack emissions
• Lower thermal pollution output
• Simple start-up and installation
• No field piping required
• No structural supports required
