Harji Dual Fuel Burner 66-54
Features
Series 66-54 Dual Fuel Burner offered in sizes 3, 4, 5, 6, 7A extended downward the range of sizes of heavy oil cold air sealed in burners utilizing the efficient “ tip emulsion” type atomizer. These burners make it possible to use the current heavy residual oils (heated to a viscosity of 100 SSU) in the range of 25 gph down to less than 2 gph ( 96 to 8.5 ltrs/hr.) with good flame characteristics with in a limited range of lean (excess air) to rich (excess fuel) operation. Low Pressure Air (36osi) i.e 63” is used as the atomizing medium for proper atomization of heavy oil (Residual Oil/Furnace Oil). Fuel can be used.- Furnace oil/RFO

Harji Dual Fuel Burner 642
Features
Series 642 Dual Fuel Burner offered in sizes 3, 4, 5, 6, 7A extended downward the range of sizes of distillate oil and gas nozzle mix sealed in burner that are stable with large amounts of excess air, on stoichiometeric ratio. Excess air can improve temperature temperature uniformity by avoiding hot spots in front of burners
Burners can be lighted at rich, lean or correct air/fuel ratio, then immediately turned to high fire. Required oil pressure at the burner is nearly zero, but a pressure drop of about 0.7kg/cm2 should be taken across the Sensitrol valve. If the furnace temperature after shutdown rises above 1000°C, pass air through the burner to prevent overheating of burner internals.
Fuels can be used i.e. Light Oil, Gas (Coke Oven Gas, Natural Gas (PNG), LPG)
For extended periods of operation on gas, atomizer can be withdrawn and stored.

Harji Fire All Oil Dual Fuel Burner 64
Features
Fire All Dual Fuel Burners are nozzle mix, sealed in burners for gas (Coke Oven Gas, Natural Gas (PNG), LPG), light oil or heavy oil. Capable of efficient operation throughout a wide temperature range, these burners are equally at home on low temperature ovens and high temperature forge and melting furnaces.
Ruggedly built for sustained, maintenance-free operation, 64 burners also provide for quick change of fuels without disturbing process operations.
Oil viscosity at the burners should not exceed 100 SSU. Minimum atomizing pressure at the burner is 14 osi for light oil, 22 osi for heavy oil.
