The most dominant characteristic of the rotary cup burner is the way of its atomization. Unlike the pressure jet burner which needs a small nozzle for atomizing, the rotary cup burner uses a cup with wider holes, meaning the structure of the rotary cup burner secures the burner from choking. By this characteristic, the rotary cup burner is capable of firing high viscosity oil like the HFO. Moreover, the rotary cup burner utilizes the centrifugal power for atomizing, which means that high pressure is need less for atomization.The low oil pressure of the rotary cup burner is safer to use when there is any leakage from the piping.
