Self Recuperative Burners are equipped with an integrated heat exchanger to preheat combustion air by thermal utilisation of the flue gases. Depending on the application, energy savings of around 50% or more are achievable. Self Recuperative Burners are applicable for Single Ended Radiant Tubes (SER) as well as for open fired industrial furnaces. The Recuperative Burners Basic which is equipped with a Tube Type Recuperator will achieve pay back within a short period of time. The Recuperative Burners Advanced with a cased Fin Type Recuperator is highly efficient and will further shorten the pay back period.
The charts shown here are samples for the Self Recuperative Burner 120 Series, recuperator length 540 mm, connecting capacity 80 kW, operation with natural gas and 10% excess air in ON/OFF-pulse mode with a duty cycle of appr. 70%. Irregular operating conditions will result in differing data.
