Light Oil Burners
The burners are suitable for warm and hot water boilers, steam boilers, hot air generators, and various types of process heating. They are also designed to suit furnaces with high back pressure. The burners can be mounted in horizontal, vertical and upward facing, or vertical and downward-facing orientation. Our burners are designed for operation in covered areas, max. +50oC. Normal operation altitude is 500 metres above sea level (other altitudes on request). The enclosure class of the burner is IP 20. Fuels Different fuels can be used depending on the burner model: KP models Light fuel oil, viscosity 4 to 12 mm2/s, +20oC RP models
- heavy fuel oil, viscosity max. 250 mm2/s, +50oC
- heavy fuel oil, viscosity max. 450 mm2/s, +50oC heating cartridge for pump, nozzle and solenoid valves
- heavy fuel oil, viscosity max. 650 mm2/s, +50oC heating cartridges as above + trace heating for the oil train
GP models natural gas, gases of 2nd family, groups H and E (equipment categories I and I2E)
GKP and GRP dual fuel burners
- Fuel properties as above, natural gas/light fuel oil
- Fuel properties as above, natural gas/heavy fuel oil
- Burners using other fuels are available on request.
Gas equipment The gas-related components of the burner are mounted according to the EN 676 standard: two shut-off valves, pressure switches (min./max.), and an automatic valve proving system. Other train equipment is available on request. Oil line Mounted on the burner, three-stage burners with four solenoid valves (one main valve and one valve for each nozzle). Modulating burners have three solenoid valves. The oil regulator for the modulating burner is located on the oil line returning from the nozzle. The oil filter is located on the suction side of the pump. The two oil hoses enable the burner to be hinged. Flame monitoring All models are equipped with automatic flame monitoring. In KP and RP models, flame monitoring is taken care of via photocell; in GP, GKP, and GRP models, it is performed via UV cell. Control devices The control automatics (control unit) are integrated with the burner. The control unit handles all burner operation phases automatically. In the event of a burner failure, the automatics stop the burner automatically. The modulating burners also incorporate a pre-mounted capacity controller. Subject to additional charge, the burners can be delivered with electronic ratio control. Silencer The sound level of the burners is low, but, if desired, they can be equipped with a separate silencer to make them even quieter. Optimising combustion head pressure loss At an additional charge, the modulating burners can be equipped with a system that optimises the combustion head pressure loss. The system reduces the amount of excess air and also improves combustion figures for partial burner loads.
