The pressure-diffuser type oil burner, handles low-viscosity heating oil below the cooking and cracking temp. It has a heater upstream of the diffuser nozzle, preheating the oil to up to 150 deg., and typically immediately before the nozzle. The nozzle union, oil pipe and heater element can be connected together in a manner such as to give good heat conductivity. The element may be cylindrical, encased by the oil feed pipe or passage and formed with the nozzle union, in a block of material with high heat conductivity, the element screwing into the block. The oil passage way run in a spiral round the element. |
