DGF oven can burn nature gas or LGP,The gas burners are placed inside the oven room over and under the baking band. The flame from the gas burners heats up the baking room. The burners operate at a zero gas pressure system. In each zone a blower sends a speed – controlled airflow through the injectors of each burner. In this way the correct amount of gas is drawn to the burners securing the correct temperature. Each burner can be selected from the control panel and turned on/off to achieve the correct settings in each zone for every product. A flame detection safety system ensures that there is no gas in the burner without a flame.in all directly fired ovens the air extraction system plays an important role in controlling not only the humidity but also the temperature across the oven band. In the DGF oven there are suction canals across the top of the oven chamber for extraction of humidity air.
