What is Flue Gas Heat Exchanger ?
This compact brazed plate heat exchanger is
specifically designed for flue gas heat recovery.
It efficiently transfers thermal energy from high-temperature exhaust gases to a liquid
medium, enabling significant energy savings in industrial and commercial heating systems.
Why use our Flue Gas BPHE?
In conventional systems, flue gases often carry away a large portion of usable heat. By recover- ing this waste heat, the system improves overall thermal efficiency, reduces fuel consumption,
and lowers carbon emissions—making it an essential component for energy-conscious operations and sustainability targets.
Features:
• High-Temperature Resistance: Handles flue gas temperatures up to 750°C ( with selected material).
• Asymmetric Channel Design: Minimizes pres- sure drop on the gas side while maximizing heat transfer.
• Compact Footprint: Space-saving form factor allows easy integration into tight installations.
• High Efficiency: Special corrugated plate design ensures optimal thermal performance.
• Durability: Built from corrosion-resistant stain- less steel, brazed with copper or stainless for long-term life.

Modular Design
This configuration showcases a
modular heat exchanger system (with shell)
The units can be combined horizontal- ly or stacked vertically. Fully custom-
izable to meet specific operating conditions.
Each module can be selected and
arranged depending on flow capacity, installation space, and performance
requirements.Ideal for scalable thermal management solutions.

Flexible Inlet/Outlet Configuration This design highlights the flexibility of gas inlet and outlet positioning:
Gas inlet and outlet can be placed on the same side for compact installation.
Alternatively, they can be placed on opposite sides for counterflow or
specific layout needs.
This design enhances adaptability in various installation environments.
