+49Gas- and fuel oil burners
Gas- and fuel oil burners of stationary boilers are intended for burning gas and fuel oil, as well as for full combustion (in combination with furnace) of fuel by creating homogeneous fuel-air mixture.Using rich expertise in designing furnace units, Powerz has designed a range of oil-gas burners. We manufacture straight-flow swirl burners with individual air feed intended for burning liquid fuel and natural gas in furnace units of hot water and steam boilers.
Gas- and fuel oil burners of this type are semi-automatic. This burner is equipped with a fuel oil burner, a peep hole, an ignition signal device and a monitoring sensor of a burner torch. Furthermore, upon request of a client, burners may be equipped with automatic ignition and flame control systems.

Using extensive experience, Powerz has designed a standard range of oil-gas burner where basic technical features are implemented in an optimal manner. When designing burners for specific boilers, we choose the most relevant burner from the range according to key parameters and then adjust the device in accordance with specific details of the project. This approach helps to effectively use many years of professional experience used during designing of oil-gas burners.

Double-flow burners (air and natural gas). Axial swirler is located in the central passage, and blades are installed at an angle between 45-55° relative to the jet axis. Approximately 40% of air is fed through the central passage, the other 60% is fed through the peripheral (straight-flow) passage.
Burner's gas distribution device has two gas feed flows. Gas is feed through the tubes distributed evenly between central and peripheral passages. Ends of gas tubes have curved heads in order to provide optimal mixture of gas and air and minimize harmful emissions. Suitable materials are used during production of burner nodes and components which are influenced by high temperatures. Burners are equipped with peep holes and tubes for installation of nozzles and ignitors. Installation site of burner torch sensor is determined by the type of a boiler depending on burner design. Parts made of flat steel and carbon steel are used to manufacture burner's air passages (except for nodes and components influenced by high-temperature furnace gases and radiation).
