Principle of operation : The fundamental concept behind a rotary cup burner is the mechanical fragmentation of fuel into extremely fine particles. As implied by its name, this burner features a high-speed rotating cup, spinning at 5000 to 6000 rpm, depending on the manufacturer's design. Oil flows over the cup as a thin film. Due to the rapid rotary motion, the fuel particles are propelled away from the cup's center in a specific pattern, breaking into very fine particles. Th
