Product Description
ASME A179 Coal-Fired Boiler Economizers of Carbon Steel to Power Station
Product Overview
The economizers consist of parallel-arranged pipes, often curved to maximize contact area between flue gas and incoming water. Flue gas passes through the boiler combustion chamber into the economizer, flowing through the pipes while boiler inlet water simultaneously passes through and exchanges heat with the flue gas. This heat transfer process lowers flue gas temperature while increasing inlet water temperature, recovering waste heat and improving overall boiler thermal efficiency.

Key Features & Benefits
- Fuel Saving: Positioned at the boiler rear, economizers reduce smoke and gas temperatures, resulting in significant fuel savings
- Improved Steam Drum Conditions: Increased feed water temperature reduces temperature differential between feed water and steam drum wall, minimizing thermal stress and extending service life
- Reduced Manufacturing Costs: Low-temperature economizer components replace high-priced high-temperature water wall panels, lowering overall boiler manufacturing expenses
