The new burners of the TECNOPRESS series, standard Low NOx Class 2 (< 120mg/kWh) gas side, cover a working range of 250 to 1,200kW.
As with all other models that use two fuels, these products perfectly complement the automatic control of the gas burners with those suitable for operation with fluid fuel; This is possible because they are equipped with an independent electric motor to control the diesel pump. Therefore, when using gas, the motor that drives the liquid fuel pump remains stopped.
They are equipped with a combustion head designed to produce diffusion flames with high irradiation power with respect to the gas side, and a reflux nozzle that allows, thanks to a regulator that varies the fuel pressure in the return and, therefore, Therefore, in the flow, an adjustment range of 1:3 is obtained in the PR and ME version. A synoptic panel on board that contains the control equipment, allows visualization of the different operating phases and any system anomalies. The flame protection system is guaranteed by the presence of a UV photocell.
