Gas Turbine - How a Flow Divider Works

A gas turbine flow divider distributes fuel in equal amounts to a gas turbine’s fuel nozzles. It’s made up of multiple gear pump elements with one inlet and multiple outlets arranged in a circle. Each gear pump element is driven by the fuel stream, which is directly proportional to the flow divider’s speed. A central sun gear connects each driven gear to the others, synchronizing their speeds. This ensures that each fuel nozzle receives the same amount of fuel. A mechanical device called a flow divider splits flow and compensates and distribute flow for all 10 or 14 number of combustion chamber. A flow divider can split flow equally, or unequally, and into more than two paths. One design maintains a constant number of flow for one outlet and directs any excess flow to a second outlet. Flow dividers are common components in hydraulic systems. They are used whenever it is important to deliver equal flow to two or more actuators or sets of actuators in a series. There are two types of flow dividers: the motor type and the orifice type. base load and peak load power plants.
