Dual-Fuel Burners

Sizes 30 and 40, version NR & Size 50, version NR

• Fuels : HFO, Natural gas, LPG.
• Stated oil throughputs are based on a calorific value of 11.24 kWh/kg for HFO.
• Plotted operational ranges represent maximal values measured on idealised flame tubes in accordance with EN 676 and EN 267.
• Stated ratings are based on an air temperature of 20 °C and an installation altitude of 500 m above sea level.
• For installations at higher altitudes, a reduction in capacity of 1 % per 100 m above sea level should be taken into account.
• Voltages and frequencies: The burners are equipped as standard for three-phase alternating current, 400 V, 3 ~, 50 Hz. Other voltages and frequencies are available on application (no additional cost).
• Standard burner motor: Insulation Class F, IP 55 protection, IE3 efficiency.
