Boiler Economizer Energy-Saving Solution Industrial Boilers Customizable Design Available
Product Description
Economizer coils are installed downstream of the boiler bank—their main job is to preheat the feed water by soaking up heat from the hot exhaust gases. When it comes to economizers, they’re always of the water tube type.
The tubes used in economizers vary based on the specific application. For example, bare tubes are super common in industrial boilers. Then, for setups like heat recovery boilers in sulfuric acid plants, gilled tubes are the go-to choice. Finned tubes, on the other hand, are really popular for HRSG (Heat Recovery Steam Generator) applications.
Typically, the feed water can be heated to a temperature that’s roughly 20 to 30 degrees Celsius below the boiler’s saturation temperature.

Application
In most commercial and industrial boiler setups, when the boiler’s running, about 10 to 20% of the fuel’s heating value gets released into the air along with the stack gases. That’s where stack economizers come in—they’re built to get back a good chunk of that energy that would otherwise be lost with the stack gases. This helps boost the boiler system’s efficiency by a lot.
When you’re picking out an economizer, there are a few key things you need to keep in mind:
• Gas-side Pressure Drop. Added back-pressure on the boiler stack affects the combustion air fan throughput capability. The economizer and combustion air fan(s) must be sized properly in order to assure a suitable system operation and capacity.
• Feedwater Temperature. The feedwater to the economizer must be deaerated and the temperature setpoint minimally at 220oF to prevent tube corrosion.
• Water-side Pressure Drop. Feedwater pumps must be sized to accommodate the economizer pressure drop. Additionally, a continuous modulating feedwater system is required to ensure proper flow rates through the economizer.
