Waste heat recovery from Fired heaters

Cold spot corrosion problems limit heat recovery. A polymer air preheater can recover heat below the acid dew point without corrosion issues.

Advantages of recovering heat below the acid dew point with a polymer Air Preheater

  • Additonal waste heat recovery
    Additonal waste heat recovery

    Cold spot corrosion problems limit heat recovery on Fired Heaters. The polymer air preheater of HeatMatrix combined with an (existing) metal air preheater enables heat recovery to a flue gas temperature below 100 °C and can boost heater efficiencies to 95% or higher.

  • Increased reliability of existing metal air preheater
    Increased reliability of existing metal air preheater

    The polymer air preheater can be installed in series with the existing metal air preheater. The polymer air preheater protects the metal air preheater for cold spot corrosion and the metal air preheater protects the polymer air preheater for high temperatures. The combination allows heat recovery over a broad temperature range with a reliable operation.

  • Prevention of downstream corrosion
    Prevention of downstream corrosion

    The polymer air preheater can be installed upstream or downstream the ID fan. By-passes in both flue gas and air ducts can be considered for maximum reliability and flexibility. The downstream ducting and ID fan will not be impacted by cooling through the acid dew point because most of the acids are removed.

  • No influence of sulphur fluctuations in fuel
    No influence of sulphur fluctuations in fuel

    Sulphur fluctuations lead to fluctuations in acid dew point. The operation of the polymer air preheater is insensitive for these variations because it is corrosion resistant.

  • Protection against seasonal temperature changes
    Protection against seasonal temperature changes

    The polymer air preheater preheats the air before it enters the metal air preheater. Therefore the metal air preheater always operates at an elevated air temperature and seasonal influences are not posing a cold spot corrosion risk.

  • Elimination existing Steam air preheater
    Elimination existing Steam air preheater

    The polymer air preheater replaces an existing steam air preheater. That means that you will not have any steam costs and maintenance costs.

Recovering heat beyond the acid dew point reduces the CAPEX and OPEX costs of future Carbon Capture & Storage (CCS) systems
