Рекуператор Теплообменник HeatMatrix_product81The HeatMatrix air preheater consists of multiple corrosion resistant tube bundles contained in a metal shell or housing. The proprietary polymer bundle design consists of multiple tubes that are connected to each other over almost the full length of the tube. This structure creates a strong rigid matrix grid that is able to resist high gas velocities and thermo shocks. The supporting connector between the individual tubes creates simultaneously a counter current flow configuration between the two fluids. This configuration improves the heat transfer by 20% compared to cross flow type exchangers.

The inlets and outlets of the exchanger are located at the side of the heat exchanger in order to allow easy access to the polymer tube bundles. These lightweight bundles are retractable from the top and can be cleaned or replaced without demounting the complete exchanger. In the case of fouling flue gas each bundle can be equipped with a spraying nozzle, which thoroughly cleans each bundle in an alternating cleaning sequence during operation.

Open-Luvo Рекуператор Теплообменник дымовых газов HeatMatrix AIR PRE-HEATER (APH)For flue gas temperatures above 200°C a combination between a metal and a polymer air preheater combines the best of both worlds

  • This hybrid design has the following advantages:
    Increased heat recovery over a wide temperature range
  • The polymer air preheater protects the metal air preheater against low air temperatures that lead to cold spot corrosion problems
  • The metal air preheater protects the polymer air preheater against high temperatures

Frequently used steam air preheater for raising the temperature of the combustion air to prevent local cold spots is no longer required with this hybrid air preheater design. A stacked or integrated lay-out reduces plot space and installation cost.
