EXAMPLE OF CHOKE SELECTION
The furnace has an effective output of 290 kW.
For a pump pressure of 12 bar, the nearest value is 288.80 kW, which corresponds to a choke of 6 GPH. If it
is a double-choke burner, divide the feed with a choke of 2.50 GPH on the first flame and 3.50 GPH on the
second flame.
If is does not have an optimum choke, it is possible, within the limits of 11 –14 bar, to adjust the pump pressure
to obtain the desired fuel supply.
MOUNTING THE CHOKE
Once having chosen the correct choke, it may be mounted as indicated in the paragraph "MAINTENANCE".
