Features and Benefits
Reduces Fuel Use and Cost:
- Recovers heat from flue gases that would otherwise be wasted.
- Heat is used to raise boiler feedwater temperature prior to entering the boiler.
Load Changes:
- Rapid changes in load demands can be met faster due to higher feedwater
temperature.
Emissions:
- Reduced fuel-firing rates for any given steam output means reduced NOx
emissions
ASME Construction:
- Ensures high quality design and manufacturing standards.
- Provides safety and reliability.
High Efficiency Heat Exchanger:
- Provides uniform fin-to-tube contact for maximum heat transfer.
- Fin tubing offers up to 12 times the heat exchange surface of bare tubing of the
same diameter.
Self-Draining Design:
- Suitable for outdoor installation.
Low Pressure Drop:
- Provides low gas side pressure drops.
- Permits use of smaller forced draft fans.
- Permits use of existing fans in almost all installations.
Gas Tight Combustion Stack:
- Provides inner casing of carbon steel (watertube boilers).
- Stainless Steel casing for the E+Plus on firetube boilers.
- Compact dimensions provide for easy installation.
Feedwater Preheating System: (watertube boilers)
- Controls cold end corrosion through all flow rates.
- Prevents the forming of corrosive acids in the economizer.
- Prevents stack corrosion.
Guaranteed Efficiency on Model CB Firetube Boilers:
- $10,000 rebated for every full 1.0% efficiency point less than guaranteed.
