Flue gas recirculation

Flue gas recirculation

Current Weishaupt burners in 4LN version meet the world's strictest environmental specifications. Burners version 4LN are equipped with a flue gas recirculation system, whose control components are integrated in a separate fan unit.

Flue gas recirculation for gaseous fuels: Gaseous fuels are almost completely sulphur free. Consequently, the flue gases consist primarily of carbon dioxide (CO2), water vapour (H2O) and nitrogen (N2) and the flue gas recirculation system does not become fouled by ash or soot.

Specially designed mixing assemblies: Specially designed mixing assemblies and digital combustion management ensure that the key characteristics of Weishaupt burners – reliable ignition, a high degree of flame stability, and safe operation – remain very much to the fore.

Dosing: The Mixingbox is worth mentioning. It combines the compact dosing unit for flue gas recirculation and the negative pressure control of the air intake. With this compact fan unit, installation work and commissioning time on site can be reduced.

Control: The FGR system is controlled by the W-FM 200 combustion manager. An additional software module ensures the return of a temperature-compensated volume of flue gas at all operating stages, reliable cold start behaviour, and the highest degree of operational availability.
