Liquid Fuel Flow Dividers

Flow dividers are used to separate a single larger
flow of liquid into multiple smaller flows. Roper
Pump Company flow dividers are specifically
designed for the electrical power generation
field. Our units are connected to industrial gas
turbines and maintain equal flows of liquid fuel
to all the turbine’s combustors.
In general, a flow divider is comprised
of a number of precision spur gear pumps
that are coupled together in a manner that
keeps them rotating at equal speeds. Each one
of those pumps is termed “a flow element�.
In operation, fuel is supplied to an inlet port
on the flow divider by a main fuel pump.
Once the fuel enters, it flows through a
common passage that feeds the inlet sides of all
flow elements. The energy contained in the
fuel flow causes all the flow elements to rotate
simultaneously and function as hydraulic motors.
Since all the gears are virtually the same size
and have very little clearance around them,
each flow element meters out an equal flow
of fuel from its discharge sides as it rotates.
Piping attached to the discharge port of each
element then conveys these equal fuel flows
to the combustor nozzles of the turbine.
