Self Recuperative Burners
The self-recuperative burners integrate an heat exchanger that uses the enthalpy of the flue gases to preheat the combustion air, reducing consumption and emissions of Co2 and NOx even by 30% compared to the use of cold air. To increase efficiency, the heat exchanger is built in highly conductive materials, such as silicon carbide (Sic), is equipped with grooves and fins and is interposed between opposite flows of cold air and hot exhausts. Self-recuperative burners, being standardized and pre-assembled products are much cheaper than a single external exchanger that requires a specific realization. Furthermore, during maintenance or in case of problems, only the single burner can be stopped and not the whole oven.
