ASME Energy-Efficient Carbon Steel Finned Tube Boiler Economizer SA213 T11
Product Description
The economizer is a kind of heat exchange equipment that absorbs exhaust waste heat to heat feed water. It can increase the feed water temperature, reduce the exhaust gas temperature, reduce heat loss, improve boiler efficiency, and save fuel accordingly. The boiler economizers are usually installed in the tail flue of the boiler, adjacent to the air preheater. In this way, the temperature of the flue gas can be lowered after passing through the air preheater, and then further reducing the temperature through the economizer, so as to improve the thermal efficiency of the boiler. In short, the boiler economizer is a high-efficiency, energy-saving and environmentally friendly boiler essential equipment.

Function
1. Absorb the heat of low-temperature flue gas, reduce the exhaust temperature, reduce the exhaust loss, and save fuel.
2. Because the feed water is heated in the economizer before entering the steam drum, the heat absorption of the feed water on the heating surface is reduced, and the economizer can be used to replace part of the evaporation heating surface with high cost.
3. When the feed water temperature increases, the wall temperature difference will be reduced when it enters the steam drum, and the thermal stress will be reduced accordingly, prolonging the service life of the steam drum.
Energy-saving principle
Add a reheating step to the cycle—it raises the average temperature of heat absorption, which in turn boosts the cycle’s efficiency.
During the startup of a boiler (specifically a drum boiler), the steam-water pipeline hasn’t started circulating yet. That means the boiler feedwater is stagnant, and the water inside the economizer isn’t flowing either. As boiler combustion ramps up and flue gas temperature rises, the water in the economizer can easily vaporize—leading to overheating in parts of the economizer.
To prevent this, a recirculation pipe is installed: it connects the steam drum’s centralized drain pipe to the economizer’s inlet. This keeps the water in the economizer flowing, stopping it from vaporizing.
